The wrench below is also of WW2 vintage, purchased for $.50 cents at a garage sale. Bid is now at $10.00 on EBay.
I had a spare complete set of early 80's vintage BMW Motorcycle tools which I really didn't need. The set was missing one small "pin spanner" (which I liberated as my set was missing one) and had a couple other extra tools included. It went for over $170.00 via EBay.
