Gil..thank you for taking the time for posting this information.
There are a lot of followers of the CanadianC3 and its successor the C3a1. C3 was trialed in 1973 in CFB Gagetown NB and put in service in 1976. It was built on a 1200TX target rifle using the Palma 1969 barrel profile. The official scope was the Kahles ZF69 calibrated to the 7.62x51 Nato. It saw service to 1985 and was replaced by the C3a1. The transition from C3 to C3a1 is somewhat "Cloudy". Officially the C3 was destroyed however it has always been rumored that some were returned to Parker Hale. It would be very interesting if you could tell us how many were in fact returned to Parker Hale.
The C3 serial number range was randomly from R-21187 to R-39519. I would be most interested in the details of your record for R-23292 and R-29813. Where these rebarrelled? Restocked in "beech", Reserialized or remarked as M82's. Did they get sold to the public? Other "R" serialized receivers have surfaced and maybe Parker Hale recovered the parts for M82's and sold off. All depends on the serial number. Any detail you have would help us better understand the C3.
The C3a1 which is built on the M87 action has just recently been retired from service however retained as a training rifle. 10x Unterl scopes replaced with Schmidt and Bender so I've been told.
Anybody have recorded numbers for the C3a1?
Greatly appreciate any information on the C3 and C3a1.
