The BR▸ totems are all very valuable these days. The Earlswood Lakes one must be especially rare. The platforms there are quite short.
That totem is something I'd like, as the signalbox there was one of the first I visited, in teenage years. But it would probably be unaffordable, and would generate an intolerable earache
There was an Earlswood Lakes sold six years ago for £500
https://mail.gcrauctions.com/sale245/lot252.html That one doesn't look quite as nice as the one in the current auction. Back then though, bidding from home wasn't as easy as it is now.
All it needs of course is two very keen people and the sky is the limit as we've seen with totems. There is a Buyer's Premium plus
VAT▸ on that which adds 18% to the hammer price so a sign where the hammer came down on a top bid of £500 will cost just under £600 in all. Then you or a friend either need to collect it or get a company to do so and send it to you (that's about £90).
Not all totems are very valuable but not much (in good nick) sells for a hammer price of less than £350 nowadays. A lot of totems do seem to be coming on to the market - I think the GWRA auction has the most in one auction to date. Helps again that they don't need to be lugged to a hall for an in person traditional auction.
