Okay, now that I have your attention , I'm trying to learn how many runs of O scale KEY diesels were built by Samhongsa. I know after Samhongsa collapsed in the early 2000's, Sam Model Tech started up with some former employees, but I don't know if they produced any models for KEY. I also know Key switched to F.M. Models after the Samhongsa collapse and was told by a very reliable source there were 4 runs imported from F.M. Models by Key.
I've owned several iterations of Samhongsa built KEY E & F units over the decades (1 FM) and the Samhongsa box labels said either "classic ser #" or "custom ser #" 78 and later "classic ser #" and "custom ser #" 85. I always assumed the numerals represented the year of import, but now I think that is wrong.
I recently purchased an AB set of E8's and the box label says "Custom Ser # 85". Apparently this is a later run of E units than I've ever owned, as the roof paint scheme is mid 60's, has a cab roof (working) flashing beacon, open coupler pocket in the pilot, working red/white flashing lights in the upper hole and shaded lenses over the number boards that hide the numerals, unless illuminated.
So, I'm hoping others here might have some experiences or knowledge that we can piece together, before this history is lost.
Thanks,
BH
