There are two sides to every story, but I was under the impression that all the brandname ‘collector’ series cars were built under commission to a North American contractor. Thus LGB as it was then, would have received payment for the production runs. This does not explain the “Coke” cars made for the European market though.
If this is the case then the items would have been onsold (most likely at a massive clearance price) to whomever is marketting the cars now. If the cars are not now discounted then someone is trying to make a lot of money with not much chance of that happening. There are brandname collectors and they would out number model railroad hobbyists many times over. Look to the Wilson Bros. Circus series made by Depot G in the mid-1990’s. Ever tried to buy a the flatcar with 2-ton Caterpillar bulldozer load? The Caterpillar collectors eagerly sought out these cars causing the price to skyrocket.
If the loyal brandname collectors have not purchased them by now then little chance of railroad people buying them.
I learned a long time ago, the LGB collector market is very, very, very small when it comes to onselling a in a ‘collector’ market and while we hear of big prices that people pay for collectables, the ‘collector’ is generally very astute with his purchases and will only pay what is necessary and the chance of a high price is not very good.
