You will have to contact SIG to find out.
Are you looking for a specific model or action type? Have you tired doing an internet search for "parts of a rifle"?
All parts are stamped with the exact same serial number, indicating that they're all original to the rifle.
We have virtually all the parts for most Marlin models. sales@countrygunsmith.net

Any gun stores at all around your parts.
Crosman still had parts available for this rifle. They also have, on their web page, a link to all their parts and manuals. try http://www.crosman.com/airguns/service/manuals
Need a detailed description of all markings on all parts of the rifle.
It would take a textbook or more to name them all.
In good condition, with all working parts, around $150.
The oceans have different names so people can refer to the different parts by name. It is the same concept as to why your body has different parts that have different names. Hope this helps! :)
See the link below it has all the Crosman Owners and Parts manuals online.
if its a 1913 Pattern 14. army rifle that's in good condition with a bayonet attachment and still works and has all the parts to it, its probably worth a few million
