A lot of people to answer to. I am sure I own a late C15A, since Canadian forces arrived in Italy late in the war. Also, the part lists shows a hoses configuration from a certain number on which resembles that on my truck. It also mentions the hose retainer spring to which Bob refers. There's a hydraulic shop a couple chilometers from my home, but here in Italy they don't have USA thread fittings, I'd have to have them made especially for me (at least 10.000 pieces). Should Bob is unable to help me out from his supplier in Canada I'll try with GMC hoses. As for the master cylinder, the one on my truck (and the one on the truck of a friend of mine too) had been relined with a brass sleeve and is quite like new. Again, the rubber parts of the correct size are almost impossible to find here in Italy, I have been very lucky to find an old automotive workshop that had a complete set still on the shelf, otherwise I'd have to throw it scrap.
It could help to look at the roof hatch, if I am not going wrong first type trucks had a square hatch while lates had a round hatch.
