I may start looking for the MK3 or 4 Super Meteor in .177, sights would not be an issue as I always use a scope due to being old and a very mediocre shot. I do seem to have collected a lot of parts for Meteors and have an experiment or two I would like to conduct... Frankenmeteor! GGGR supplied me with a lovely stock years ago which will have to be used.

Thanks for the information Dorn, some of this stuff is very obscure and not easily accessed.
