Parkpre Mountain Comp

[furiusd]

I've got this old Parkpre Mountain Comp which has spent most of the last 15 years in a cellar. I've been using it for my commute for the last couple of years now but parts are getting tough to find so I'm thinking of selling to get a more standard road bike. I can't find any information on how much it is worth however. Anyone have any ideas where I can get the info?

I can't find a way to attach more than one pic. the Serial No is 55092088

thanks!
