Unknown part for T-17

[Phil Waterman]

First, Hanno the parts are yours if you want them, would rather trade for parts than send money back and forth send me a private message with address. Looking for small stuff for the my Pattern 12 that I can’t find over here.

Second, now that we have identified that this looks to be brake system parts, the vendor who donated these had two strange brake booster units that look like a variant on the hydrovac units also covered in cosmoline. Would any body know what the brake units would look like, I’ll try and get pictures.

Third yes the dimensions are in inches.
