1960's-70's set of 8 Winchester promotional commemorative buttons/cufflinks

I hope i posted in the right place...my bf's buddy worked for Winchester in Ct for years. at some point (from the style of the box i'm thinking 60's-70's) they came out with this promotional boxed set of buttons or cufflinks.

They are brass plated metal and in excellent condition.

I've seen similar pieces on ebay but they looked homemade and not in boxed sets.

any help is appreciated...i am going to sell these and would love some guesstimate of rarity or value. thanks!

 

No one since 1:47 pm??!
May need to be in another forum.
I think they are pretty cool!
I saw a lot on Etsy but none in the box.
You might get some pricing ideas there.
