Red Bug Motors needs a used Universal Growler for armatures

Martindale TYPE U-2 UNIVERSAL ADJUSTABLE GROWLER or similar. Would like a used but useful growler for our repair shop. I spent day’s turning, undercutting by hand and all else. Re-installed the AMD motor and CRAP! It was shorted! So depressing. Need this piece of test equipment so I don’t have to go through that again. Thanks!!!

I have one but not sure I want to sell it.
Did you look on ebay? They are pretty common.

Thanks. I did look on ebay but couldn’t find what I was looking for. Mostly antique growlers.

Antique no good? That’s what mine is.
Not much to go wrong with them.
