Keil-Line was a major player at O Scale shows years ago. A lot of metal castings. The business was purchased after the owner passed. Not sure if it's up a running yet. You still may be able to find them through Walthers or P&D Hobby Shop.
I have I think a pack of 4 table lamps from them. I'll try to shoot a pic today.
Apparently someone purchased the business and is up and running. I came across their products on eBay. They are now Scale City Designs.
A while back I purchased their unpainted cast luggage set.
By the way, a forum member posted a thread about how he detailed the interiors of his cars using some items found in craft stores like Michael's.
