Thanks FredC and everyone else for all of your input on this issue.

I found the item pictured below on ebay a while back but had rejected it because it would require the use an old fashioned military style sling with simple loops for the forestock which eliminates quick disconnection as an option and in addition would require some significant and rather precise modification of the stock to install. Butlersrangers ad posted a photo of a similar fix using a 1903 band earlier. The seller on ebay had this part listed as originally belonging to a Krag, though I'm uncertain if it actually is. However, it may be possible to make this part work with some careful stock modification. Any ideas?
