I believe the rifle in question was on the EE. I likely would have bought that one too, the price was very reasonable (was it $600 or so?). You must have beat me to it.
They come for sale so rarely it's difficult to get a real sense of their value. The market for trainers is a very narrow one in Canada, you'd likely have a hard time getting more than $1000 here. $500 to $1000 would be about right. If the rifle is all original in excellent condition, which the one on the EE appeared to be, it would most certainly fetch way north of $1000 in collectors circles (US) or on Gunbroker.
Post some pictures already!!!!
