Hi, Haffy here. I'm new to the forum, thought I'd throw out a quick post. I've taken a liking to the older machines, currently have a 444 that I'm just finishing up a refurbish on. It was a shell with a couple seized engines that I managed to get my hands on cheap! She's now up and running, just working out some bugs. It's not returned to original specs, just built to look cool and much around the house with. Any other 300, 400, 500 or 600 enthusiasts out there?
