Honda front master cylinder identification

[Shermanator86]

I got this master cylinder from a salvage yard and it was already off the bike so I have no idea what it came off of, I've been told that all the early 70s should be the same but as most parts go by model I would like to get a specific model if I could so I can get ordering parts. Thanks for any help

not sure exactly what it's from but it looks an awful lot like the MC used on the early CX500's (except the CX MC was all black). single pot/single caliper system.

I'm not sure what the difference is between the kits. So long as it suits a 14mm Master Cylinder it should be OK?
I've rebuilt 3 master cylinders, each 14mm.

The kits I've gotten from various suppliers always seem to be a little different, some include the little piece of wire to hold in the dust cover, some don't, some have a washer wider than the hole, some don't.

In cases where either is missing or the wrong size I file it down (washer) or substitute it with the part from the removed MC (wire piece to hold in dust cover).

The main thing is to replace all the rubber boots and plunger, c-clip, spring etc with the correct sizes.
