Not sure what Canadian dollars were worth back then, but that sounds like a really good price for an all-matching mint rifle. For all my fond memories, they have always been overpriced by comparison. I also had an FN Cavalry Carbine in 30-06 that served me very well, and it was in very good shape, for only $75.00. Same length barrel as the No.5, and with a turned down bolt, but nowhere near as slick. Still a great little rifle all the same.
I see Jungle Carbines advertised fairly frequently on sites like Ozgunsales etc, but all the collectables are at least $2,000.00 plus, and the rough or non-matching ones are still fetching @$1400, plus the fakes that have a habit of continually showing up.
I'd have another one tomorrow, but like a 70's Colt Python, I just can't justify the price on something I'll probably never use again. Only Fallow deer in Tasmania, and I don't need another .303 for them.
