The end of Langs will be a problem and at the moment I have no idea of what will replace it, I have over the years bought a few items via a surrogate bidder but I have no idea who is capable of bringing out the rare high end items.
In the UK we have Neil Freeman's Angling Auctions and Mullocks. Neil has finally gone online and is still bringing in very rare items and some high end US tackle. I do not know if he will return to in room with online.
Mullocks has almost changed hands and the new owner want to hold in person auctions with on line bidding. There are plenty of items coming in to auction, mainly due to older collectors either dying or cashing in.
I hope someone can fill the gap that Lang's will leave.
