Bach 36 conversion: does anyone recognize the work?

[biggiesmalls]

I came across this Bach Corp. 36 open wrap conversion for sale, and I'm curious to find out who did the conversion (the seller has no idea).

Does anyone recognize the work?

Thanks and Happy Holidays.

Those L braces look like work I’ve seen here before but can’t put my finger on who.

The most curious detail to me is the brass ferrules.

John Sandhagen perhaps? I could be mistaken.

The wingnuts are like the ones on my 88H that was converted by Chuck McAlexander at Brasslab.

Brasslab was my first thought. The satin finish work looks exactly like a Brasslab 72H open wrap conversion that I had before the Pandemic. I asked the seller to look for the Brasslabs name etched into the F-attachment tubing, but haven't heard back from them. The "Brasslab" etching in the 72H tubing was so faint that I owned the horn for several months before I even noticed it

Yeah looks like it could be from chuck. The z brace looks like something another NYC repair tech did for me a long time ago on a 3B+…

The Z brace is for any horn that went from being a straight horn to not being straight, I've seen it from more than a few techs.
