I just picked one of these up on eBay and I look forward to running it. It seems as though the early ones are a bit rarer, and I haven't been able to find much information about them. Were there any known operating issues with these that I should look out for?
The one I bought was said to have come from Richard Kughn's collection and is new in the box, so it doesn't really have any known issues. I've been wanting one for awhile, and they're neat looking little engines.
