Just a 'nosey old bugger' thread to ask who uses a scope on their 70's & 80's air rifles, or if you prefer to stick with the open sights fitted?

I'm looking to start collecting the odd older rifle and will likely mount a period scope on at least one, but also like open sights.

First rifle on ze list is a Mercury of some description (it's the first rifle I used as a lad) and to be honest I'd like something like a 4x32 scope for it but not sure I'd want to change the looks by removing the open sights.

So, what do you put on your 'collectibles'?
