Yup, the bolt action 11 & 12 are definitely the scarcest of the Nylon family.
Prices are off the hook on them. (I wasn't aware that collectors were paying up to $700 for the bolt-actions either!
If they handle like the semis and lever actions, it's gotta be a sweet little rifle.
I think I would be very tempted to hang onto it too. They've been out of production for many years and prices are almost guaranteed to just keep moving up.
