Some believe that as they have spent time developing models that time has value.
For those folks, I don't expect them to participate.
This is not a needed source of funding for me. So i have no issues sharing.
However, I don't have a ready easy to find inventory of items. I have maybe hundreds of models that are not well-organized because I was making things on the fly.
Many or a lot of the things I made I don't use because I have revised my designs or layout plans. It's a very iterative design process. So I'd be losing money if I was a manufacturer of Ogauge products. Gladly I'm not.
Still again I have no issues sharing.
