I have a (70's I think) BSA Mercury, which was polished internallly, resprung and new washers etc about 3 years ago. The blacking was knackered so I made a nice job of spraying it black. The stock was Nitromorsed and plainly varnished. It has 2 piece mounts and a Webley 4x32 on it. It looks a nice job.
The lamp is a Deben Tracer Compact electronic with on belt battery pack. The original battery is fubar so I have got another bigger battery for it.
The lamp is in great nick and had a red filter, all leads, scope mount and charger included. My nephew is interested in buying them.

The question is, what is a fair price to charge him?

Thanks for any information forthcoming.

John
