I am not sure that the market is going to drop dramatically on the real top end items. Many of those that can afford them are untouched by the market and indeed many have made a lot of money selling short.
The prices paid in London just a couple of weeks ago seem to bear me out on this.

However this is very much a buyer beware market, especially on BA rifles. I see so much shit going at inflated prices I can only conclude that there is a large tart it up, fake it up, mark it up opperation going on overseas. Other members that have been at the sales with me will agree that redeculious prices are acchieved for items that have no use BUT the above. I have seen things sell, completly and unredeamably pitted and ruined internally and externally, that have no value apart from their serial number

I have seen personally, items advertised that I have passed on, on behalf of clients that asked me to examine them, cheeply refinished and advertised as good/origional on websites following auctions.

"Wouldent pay more than $5000 for a .275" I have seen a number sell at Ł600-800 and they dident deserve that.

This does not just apply to Rigby's although I have a particular interest in them, but to many many items.
