See eBay listings 113415388445 and 123521333211. I see no evidence of provenance. However what I do see appear to be cut from unusually heavy stock and in the form of closed loops. They appear to be 8-level (3-sprocket-5). Do these make sense for use on a Univac system? How so, and which system(s)? Happy Post-Festivus, paul
