I have an old, cosmetically battered Hertel draw scope here which, although it looks like it has been run over and then chewed by the dog, has a surprisingly good view through it. I had been recently trying to source an eyepiece to replace the cracked one, ( no joy yet, answers on a postcard please..) and I've heard that Glasgow binocular repair can no longer service these. I thought I might have a go myself at disassembly and cleaning but wouldn't know where to start really. Has anyone here done it, and if so could you share any wisdom?
many thanks
