Bovington got back to me and were very helpful, but unfortunately unless you have the 16 KA 00 style British Army reg. no. you're kind of out of luck as no records were kept by hull number.
They did send me scans of a couple of cards the rest of us might find interesting - and it shows what they have to work with. They're manual file-card type records which have been pencil-erased and rewritten and erased and written again as assignments changed, I imagine - but the reason I asked for them is that *after* Canada had taken delivery of its brand-new orders we got at least a couple of used ones out of British Army inventory in 1963. Unfortunately it doesn't really specify where they went other than "Can Bde" - but interesting I've never heard mention of it until now.
You can check out the cards here:

(ps. the "s/o" is British admspeak for "struck off" or "sold on" - and apparently "FARELF" is Far East Land Force - or gear pooled for the Malaysian Emergency, apparently surplused from Hong Kong.)
