There was a recent auction on eBay where Tel. Sighting C No. 67 Mk I serial number 15-C sold at 2700 GBP (equals roughly 3650 USD or 3100 Euro as of today). It seems that this particular scope did see quite some usage. Well, for reference, here the link to the ended listing: Tel Sighting Co No.67 Mk1 WW2 Sniper Scope 3.5x24 C.G.B 91 GA 1944 15-C Canada | eBay UK
