90L8203 is in my care and custody, with matched REL CNo.32 Mk III scope, numbered No.8 Mk II case, and marked No.15 chest. Scope serial number to follow. This one's provenance is strong: purchased from a surplus store in Montreal in the 1960s by my father, who paid the warehouseman extra to find the matching scope number in the loose pile, and inherited by me. Unfired but known to be accurate on a 6x6 target frame at 1000yds.
