Very much doubt Unit issue records have survived.
"...October 9, 1963..." snicker. I've done that. Long ago, in Toronto, Ont., a couple crates of Spencers were dug up by construction guys working on the site of an old CF Militia Armoury right in downtown TO. Right behind City Hall. Said Spencers promptly disappeared on a 'finders keepers' basis. The TO cops requested the rifles be returned, no questions asked. Never did hear of a single one reappearing. No records of 'em even existing.
