I found an Ebay ad with 14 misc. wrenches, it included kawasaki and Yamaha wrenches and had the K0 cast shock spanner and correct three end wrenches.
I also got 3 extra 8x12mm spanners, and have many of the later tools collected in my quest for a full K0 set. One 8x12 with the big HM logo and two with the smaller HM logo. I would trade, looking for other correct tool kit parts. Tool bag, spark plug, file, red handle, extension handle with the hole etc.
The newer size wrenches have the big HM logo so is it safe to assume the smaller HM logo is older?
Any tips for cleaning/polishing without removing the finish? I'm doing a vinegar test cleaning. Scotchbrite/WD40 seems to help but sure is messy. I worry about removing the original finish, a brass scrub brush removed the crud but leaves the patina.
