Where the model number appears on a Blessing trombone

The model number on a Blessing trombone is stamped or engraved on the bell — the wide flared end of the instrument. Look on the inside surface of the bell, near where it connects to the slide. The number is usually a two or three-digit code, sometimes followed by letters, and may be accompanied by "Blessing" or the maker's mark.

If the bell marking is worn or unclear, check the slide tube itself. Some Blessing trombones also have identifying marks on the outer brass tubing of the slide, though these are less common than bell stamps. The model designation helps you identify the trombone's size (tenor, bass, valve), year of manufacture, and original specifications.

Key Takeaways

  • The model number is stamped inside the bell, near where it connects to the slide tube.
  • Blessing model numbers are typically two or three digits, sometimes with letters, and appear alongside the maker's mark.
  • If the bell marking is faded, check the outer slide tubing or contact Blessing directly with photos of your instrument.
  • Knowing your model number helps you find replacement parts, repair specifications, and resale information.

Why you need the model number

The model number tells you what kind of trombone you have and what parts fit it. A tenor trombone model number is different from a bass trombone model number, and they use different slides, mouthpieces, and valve configurations. If you need a replacement slide, a new water key, or a repair manual, the shop or technician will ask for the model number first.

The number also helps you research the instrument's history and value. Blessing made trombones from the 1920s onward, and different models from different decades have different market prices and collector interest. If you are selling or trading the trombone, the buyer will want to verify the model.

How to photograph the model number if it is hard to read

Use natural light and angle your phone or camera so the light hits the bell at a shallow angle — this makes the stamped or engraved numbers cast shadows that make them easier to see in the photo. Take several shots from different angles. If the number is still unclear in the image, zoom in on the photo on your phone or computer to read it more carefully.

If you cannot read it even in a zoomed photo, take the clearest image you have and email it to a Blessing repair technician or a trombone repair shop. They often have experience reading worn stamps and can identify the model from the bell shape, slide configuration, and other visible features even if the number itself is illegible.

Common Blessing trombone model numbers and what they mean

Blessing used a straightforward numbering system. Models in the 60s range (like 60, 61, 62) were student and intermediate tenor trombones. Models in the 70s range (like 70, 71) were professional tenor trombones. Models starting with 8 or 9 were bass trombones or specialty instruments. Some models also included a letter suffix — for example, a model might be marked "70A" or "62B" — which indicated a specific variation or year of production.

The exact meaning of each number varies by decade, so a model 70 from the 1950s is not identical to a model 70 from the 1980s. If you need precise specifications for your instrument, include the model number and any visible year markings when you contact a repair shop or the Blessing company directly.

What to do if you cannot find a model number

Not all Blessing trombones have clearly visible model numbers, especially older instruments or those that have been heavily used. If you cannot locate a stamp or engraving on the bell or slide, look for other identifying marks: the Blessing name or logo, any patent dates stamped into the brass, or maker's marks on the water key or valve casings.

If no number appears anywhere on the instrument, a repair technician can often identify the model by examining the slide design, bell profile, valve type, and overall construction. Take clear photos of the bell, the slide mechanism, and any visible markings, then contact a Blessing specialist or a local trombone repair shop. They may be able to narrow down the model based on physical characteristics alone.

Using the model number to find parts and repair information

Once you have the model number, search for it on Blessing's official website or contact their customer service. You can also search the model number on trombone parts retailers like Dillon Music, Woodwind and Brasswind, or local repair shops. Many shops keep catalogs organized by model number and can tell you what slides, mouthpieces, water keys, and other components are compatible with your specific instrument.

Repair manuals and technical drawings for older Blessing models are sometimes available through vintage instrument dealers or trombone forums. If you are planning a major repair or restoration, the model number is essential — it tells the technician exactly what the original specifications were and what parts will fit without modification.

Frequently Asked Questions

Where exactly on the bell should I look for the model number?

Look on the inside surface of the bell, near the point where it connects to the slide tube. The stamp or engraving is usually small and may be partially hidden by the connection joint. Use a flashlight and angle it to create shadows that make the numbers easier to see.

What if the model number has letters after the digits?

Letters after the model number indicate a variation or production year. For example, model 70A and model 70B are both in the 70 series but have different features or were made in different years. Include the letter when you search for parts or specifications.

Can I identify my Blessing trombone without the model number?

Yes, a repair technician can often identify the model by examining the slide design, bell shape, valve configuration, and any visible markings. Take clear photos of the bell, slide, and any stamps or engravings, then contact a local trombone repair shop or Blessing directly.

Are Blessing model numbers the same as serial numbers?

No. The model number tells you what type of trombone it is (like model 70 or model 62). A serial number, if present, is a separate marking that identifies that specific individual instrument. Not all Blessing trombones have serial numbers, but most have model numbers.

Where can I buy replacement parts for my Blessing model?

Once you have the model number, contact Blessing directly, or search for parts on retailers like Dillon Music, Woodwind and Brasswind, or local trombone repair shops. Many shops organize their inventory by model number and can confirm compatibility before you order.
