I’ve occasionally used auctions over many years of collecting but not too much these days.
Sometimes you can pick up the odd l, nicely priced rifle, but getting harder to achieve this these days. If you’ve not bought at auction before, consider:
1) Estimates are usually quite low..aimed at attracting bidders, not often reflective of eventual hammer price
2) Fees often add nearly 30% to the hammer price
3) Collection must normally be within a few days before STORAGE charges apply
4) Delivery is not always offered, so has to be arranged, via RFD, at additional costs all round
5) Gun condition can sometimes be disappointing

Good luck if you choose to go for it….set your top price though (it’s easy to get carried away!)
