Oh, absolutely, Mike. I just didn't want to pay more than about £10 considering I was planning to cut the model up. Above that price I would probably make something myself. Having seen the final price I wondered if the model was something special, that's all.
Steve - yes it was in a yellow box. I didn't know LGB boxes were ever that colour, and it did look "old" or tinplate-like in your description. I wasn't planning to use the track isolation feature as I was hoping to make an American style train-order board out of it, which would have meant flipping the arm over to the other side of the post and altering the arm itself. With all that speculative work to do, which might not have worked out anyway, you can see why I was unwilling to pay top rate.
