Rad is indeed a symbol of the growth of the RCAC. He was an anglo born in Gaspe, who led (not joined or served with) the 27th Armoured Sherbrooke Fusiler Regt. They were an officially bilingual regiment, long before official biligualism became the fashion.
I forget which brigade they were, but they landed late on DDay. He worn a DSO (IIRC), and his contribution to crew competance was to post replacements into his Sqn HQ Tp. He'd leave the admin to the staff, and drill the new crews before moving them into the rest of the sqn. He'd go out and have range days shooting up wrecks behind the lines, giving the men a chance to see and feel battle beforehand. He was CO too.
His legacy is Tank Bomb on the parade square in Sherbrooke, Quebec. She served from DDay to VEDay without getting knocked out. No other Allied tank has that distinction. To learn more, google Tank Bomb and see what comes back.
Any Rad souvenir has a depth beyond the fact it is an Inglis.
