1. Factory color depended on the year. The one you bought is "Little Delta Green" which first appeared in 1974. It is a brighter green than the earlier "Moss Green".
2. Thin leather would be ideal. I always thought something like shoe tongue leather would be good. It's just a thin pad to reduce rattle and protect the limb butts. You will see the area covered on the riser by the old glue line.
3. The Bear catalog CD, whether or not there are Bears on the latches, the presence or absence of a raised button coin, color etc. It's a lot of speculation.
BTW, I need to get to the Post Office!
To all my pals on here, sorry for my long absence from the Collectors Forum. I'm glad to see it back up, with all our work, pictures, and B.S. intact! I've just not had a lot of online time lately due to working shifts again, and other obligations. All is well here! CKruse
