Do not over think this...eBay...inside a refurb first stage.Do you happen to know where I can get a piston back-up ring for a 3105? If I remember correctly the little piston O-ring is an unusual size too. I have not been able to find a kit for this reg so it has become my nail-gun regulator.
You need to separate the concepts of "service replacement parts" from "the rest of the regulator parts". Multiple perps provide service kits baggies, only Sherwood can provide the other parts and only to recognized dealers if "Sherwood still has the parts". My LDS started telling me that Sherwood does not have parts about 15 years ago. They were trying to sell me a new regulator, so who knows how many parts Sherwood has...
I buy service kits off ebay.
If I discover that I need a "non-service" part, then I buy a complete reburb unit off eBay. My last piston "part" cost me about $45 and came assembled inside a complete working first stage...YMMV
Do not get overly focused on hard to get individual parts, when complete assemblies are available for a reasonable cost..
I discovered this outlook many (MANY!) years ago as a poor student after someone tried to steal my beloved hardtop 1967 Chrysler New Yorker beater and they drove it into a telephone pole after I threw a brick at them through the drivers window. Insurance wrote the car off for $500 and then gave it back to me (saved them paying more towing costs from the impound to get it crushed). I bought a complete replacement parts car for $200. Stripped what I needed from the parts car and got $35 from a wecker for the remaining hulk.
