Brad,
This might not be what you're looking for, but I can relay my experience and history with the Beaver Creek Express Boxcars. Beaver Creek was primarily an HO model importer in the late 80's up into the mid 90's and did only a few projects in 0 scale. About 1994-95 they announced the Union Pacific Express Boxcars (unique and never done before) and being a UP modeler I had to have one.
There were three paint schemes (Yellow/Gray, Tutone Gray and Route of the Challengers Gray/Red) and two or three types of trucks (Allied, Symington and another). I order six, two for myself and the others for members of the KCMO O module group I belonged to at the time. I was a very small brass dealer at the time so we all got one for dealer cost, which I believe was around $195 painted. I prepaid for all the cars up front myself, as this is what Chuck required.
The express BC's were imported unpainted and Chuck had an assortment of custom painters who painted them for Beaver Creek just like OMI did at the time. The paintwork was very, very good as you have seen if you own stock models.
Just after these cars arrived in the USA Chuck had a heart attack and passed away. This was before email, so magazines, snail mail and word of mouth was the only way to learn news of this sort. When I heard the news I called the number I had for BC but no one answered the phone. This went on for weeks so I started checking around with other dealers I knew.
I believe it was Bob Janzen (sp) who gave me good telephone numbers and after a month or so I spoke to Chucks wife who obviously had her life turned upside down and didn't know what she was going to do. We had many long distance conversations and I offered some suggestions and even offered to accept my cars unpainted. I figure unpainted cars was better than none, which still seemed to be a possibility.
In the end, all turned out well. Chucks wife made arrangements to have my cars painted and I received them a few months later. I heard rumors not everyone was this fortunate, but I can't remember any of the details any longer. I was just elated I didn't lose $1200 that I couldn't afford to lose at the time.
I know BC offered some O scale "old time" passenger cars in a set of 3, but don't think they did anything else. Chuck certainly could be proud of the Express Boxcars as they are great!
