Bach 42 Bell Stamping
In my feverish efforts to assemble a mixed family of Bach horns, I have run across a Bach 42 with what appears to be a stock valve, but the bell (Corporation) simply reads "Bach 42," as opposed to say "Bach 42B."
Is this a definite sign that the valve was added to a straight 42? If so, there is no sign of the modification on the bell, so maybe it was also relacquered?

Bell stampings almost never reveal what the horn was built as. It's almost definitely stock.

Re: Bach 42 Bell Stamping
I have never seen a bell marked "42B". They're marked "42" if they're yellow brass "42G" if gold brass, regardless of there being a valve on the horn or not. They don't make bells specifically for straight trombones or valved trombones

Re: Bach 42 Bell Stamping
Three more examples that prove the lack of rules:
corp 42 bell, from a stock 42B:

corp 45 bell, from a stock 45B. These were not ever offered as a straight 45, no reason to leave off the B:

corp 50BG bell, very clearly gold brass, only marked 50B:

Re: Bach 42 Bell Stamping

Re: Bach 42 Bell Stamping
actually now you mention it, I do recall seeing a few like that too. i could be wrong but arent those usually like super early horns like NY or early MV era? i seem to recall seeing it mostly on trumpets. i could be wrong that in some cases they actualy didnt put the model number but actually the mandrel number?Burgerbob wrote: ↑Thu Apr 24, 2025 12:04 pmEven funnier, that's not always true either!

Re: Bach 42 Bell Stamping
Yeah, I try to catch myself. I think any time anybody says “Bach never did _____” we immediately find an example to the contrary. Them guys would do most anything for money or fun.
Now, to build a double slide to put this thing in Eb so that it can actually leave the house more often…

Re: Bach 42 Bell Stamping
Speaking of Bach stamping, I saw a new 42BO at a local store yesterday, and I couldn't believe how weak and ugly todays Bach bell engraving looks.

Re: Bach 42 Bell Stamping
I agree Dave. Are those new engravings stamped or laser etched?

Re: Bach 42 Bell Stamping
This is what is being done on the new trumpet models. Laser etched. I think it looks better than some of the single points engraving they have used previously. Still not as classy as the old stamped version
Reading on the trumpet herald that some believe the stamping can harden the metal, and reduce the resonance. I've also heard the idea that the area of hardened metal was what gave Bach bells some.of their character.
