Interesting ... those parts are fairly easy to find here in the US. The
only part not readily available is the cross-over tube on the "type 1"
calipers ... but they are relatively easy to fabricate.

It's possible some of these were alloy, but all of mine have been cast iron.
Heavy buggers, too. But IMO they work very well ... even with an entirely
stock system and wide, sticky tires I have no trouble locking the front
wheels when I want to. The bigger rotors (than the "Type 3") may help, too.

Pads are the same, but the springs & retainers are different.

It's been a lot of years now ... haven't had to touch a caliper since I
switched to silicone brake fluid over 10 years ago ... but I have done the
job and I don't recall it being all that hard. It does take some finesse to
keep the piston from tilting as you slide it into the bore. If it starts to
tilt, you must immediately apply pressure only to the opposite side to
straighten it out, or else you'll have to remove it again. Generous
lubrication with silicone brake fluid or brake grease helps too.
