A lot of people seem unwilling to put their neck on the line and suggest valuations these days however here goes.
Bear in mind these valuations will be rough based on average condition sight unseen...
BSA Meteor £ 60-£75
Webley Osprey £80-£95ish
Webley MkIII £95-£125ish
I would suggest that all those prices were 'plus post' of around £12 per rifle.
Anybody disagree with the above, please place you ideas on this thread
