How long has Bach made lightweight slides?

[BrianJohnston]

Has Bach made lightweight slides since the New York and or Mount Vernon era’s? Or did this start around the corporation era?

LT slides were absolutely made in the MV era. Serviced a couple years ago including an amazing sounding LT50 slide with a superb leadpipe which I think the owner kept after he sold the horn.

Not sure about the NY era but I have heard of NY small bores having LT slides but cant confirm they were original. I believe a member of chat who is s big collector has a 9" gold bell NY 50 with an LT slide, need to check.

Nickel lightweight slides exist in at least MV era. Going to NY, I know there are factory lightweight brass slides (essentially no oversleeves). I don’t know how early the nickel slides go.

I have seen two? Nickel lightweight slides that seemed to be original to a NY era trombone. Serial # made sense but who knows?
if they were bought with original outers in the 40s then several years later someone went a little further up from BX to MtV to check out the latest in LT outer slide tech
