From the few examples of the Corwin Enfields I have seen, I have to agree 100%. The ones I saw were Factory Through Repairs, done by Canadian Arsenals around 1960. Your rifle shows it has low cut wood. Normally that is only found on a 41 or earlier 42 rifle. Yet on the Corwin site, there was even a 1950 dated rifle with low cut wood. One would certainly expect a low cut wood rifle to have the early machined rear site, yet yours shows the L site typical of mid war production. I have noted the Cdn Arsenals acceptance stamp on the forestock as well as the original C/l\ marks. Hard to tell by your photos, but it also looks like you have one machined band, and one fabricated band.
The sure giveaway if it's a rebuild will be on the wrist. If there is a little letter and 1, 2 or 3 numbers stamped somewhere below the serial number on the left side of the wrist, that seems to be an indication the rifle was FR in Canada. The point behind the FTR was to make a serviceable rifle, and not to be correct as to the various features supplied to the rifle.
Personally I thought the rifles were priced towards the top of the market. Had a FTR rifle been laying on a table at a gunshow, I think it will likely have been visiting many, many gunshows before it sold at around the $1100 price point, which is what a Corwin rifle ended up costing if you were paying HST and hipping.
Your mileage may vary.
Judging by the examples I've seen, this is mostly the case.
However some people got some really nice virtually unissued ones, with all matching parts and correct features.
Many were however updated and refurbished, but while retaining their original matching bolts etc. Some also got parkerized bands and magazines, this may have been done here, but I actually suspect it was done by the NATO ally to whom these rifles were given.
After all, they were used by the NATO ally's Navy.
