Hello Starfire.
I knew that mounting would be difficult however I saw a video of a guy that put a Marx motor in a 1700. It ran great. He did the mount by making a brass fitting on the top of the motor and tapped it for a 2/56 bolt. I know the 229 is not a very tall motor but they run so well. I thought with a little work and some brass I could make a bracket. I've been looking everyday on ebay and just the internet. I can't find a 1700e motor anywhere. I did find a train store that say they have in. I joined there site only to find it was 'OUT OF STOCK'. Plus they wanted $ 149.00 for it.
Just trying to get some power to one of the 1700's that short a motor.
