Just bought a Crosman 1377

Crosman should support it, just like they support the Quest 1000 - a re-badged B19 - with just about any part you could imagine. They also have good parts support for the Benji-Legacy 1000.

The only excuse I can imagine is if the OEM is refusing to supply THEM with parts. At that point, Crosman might have their hands tied...

you can only do so for so long befour the parts run out. Once that happens you are done. And I can attest that getting parts from mendoza in mexico is difficult to say the least.  
Bottom line: You can not expect a company to support discontined items forever. After a reasonable time parts and service are gone while old/new stock can be found at just about any time. As for the warrenty cards and paperwork? those are usually collectable in older guns so I doubt anybody will be trashing them even after the guns are 20 or 30 years old.

Below is my RM377 the Wal-Mart version of the Crosman RM277. It has the distinction of being the ONLY mendoza Air Rifle that I know of that has been BesTuned. It is a smooth slick shooter and has been compared to a tuned R7. I know I like it the action and trigger pull are 100% improved and the gun is a joy to shoot. One of these days I will mount a peep sight on it.
