Just don't buy anything from Modesto, CA
Just barely joking, (if I am at all)
Honestly,
I'd say it's logistically impossible, even if anyone/everyone ever actually wanted to do it. There would need to be detailed macro photos of bare parts from every angle and every manufacturer of every type, and then you'd have to have a consensus of was really was a correct part. Think about it. Alost every authentic rare (now faked) part is installed in someone's carbine.
'IF' it could actually be done, and a consensus of true experts agreed, and a part was measured, etc, etc, and then a permanent database established here with this info, the fake parts
would get better. It would make it even harder to find a real parts.
Common sense, and experience is the best tool when learning what is real or not, Rocky.
The rarest parts became so freaking expensive because the
are rare. They aren't available by the bulk on eBay or Gunbroker.
Authentic type I push safeties floating around are rare as hen's teeth. Type I safeties with original 'EW' markings almost non-existent.
Almost all of these rare parts were removed and discarded 60 years ago. They were junk. Metal recycled at best. They weren't saved in baskets by some speculator betting they'd be worth a fortune 60 years later when these guns became collector items and every kid on the block wants a type 1 safety and a type 1 barrel band like they saw on Saving Private Ryan.
Most authentic carbines were rebuilt. The few carbines that did escape rebuilds still have the parts inside them.
Authentic loose parts do not have a good finish, or any finish at all. They're beat up and worn with a real 60 year old patina, not polished with a scotchbright pad to show a little wear or bare metal on the edges.
An authentic rare part is found in the back of an old box of old junk box under a table of an old one owner gun shop who's owner passed away 15 years ago. One part.
Authentic push safeties are just like authentic WWII
German helmets have become, and sold almost exclusively between collectors and seldom if ever found on eBay.
German helmets cost so much because they are
rare - That makes them 'cool' so everyone wants them. The market for fake German helmets was supplied by everyone wanting something rare. There are only so many to go around.
I collected USGI helmets and the same thing has happened to them now. Every piece is reproduced now, and it takes an expert eye to tell what's real or not, but common sense is the best tool, (and they're seldom found on eBay)
A fluke does happen once in a great while, but what are your odds? I don't see why anyone would spend $100+ for a part they know is probably going to turn out to be fake. Maybe they try to fool themselves, or think nobody will notice?
Then they find the part is fake after they pay someone over the internet and become upset?
I honestly don't know the answer. I know it ruined helmet collecting.
I honestly don't know why all these type i parts are needed in the first place though.
I know one guy is CA has become wealthy though.
