I don’t know what the sales were for MTH when they shut it off last year. I watched as they first dove into HO scale and now S scale with a full product catalog. I wish they would release 1 fraction in G of what they just did in HO scale.
I bet it wouldn’t sell as good. In the other scales, especially O gauge, a customer will pre-order a product a pay a premium for the latest greatest things. Most guys I know in G gauge, won’t buy something unless it’s in front of them. Even then and most of the time, it has to be a great deal.
