Greetings, I ordered the Nm YsteC Ge 4/4 (Crocodile) in 1/87 which is narrow gauge HOm, and it almost fit over the Bemo 1258 000 chassis, but was just a bit too small on the inside. There are two ways to resolve it for HOm: 1. would be to match the Bemo dimensions internally with thinner walls. The Bemo chassis is 27 mm wide and 125 mm long with curved ends, and 7 mm deep. 2. A resin chassis could be made to accommodate the Bemo bogies and motor. If it helps I can send a Bemo chassis to modify a 3D chassis from to complete the project. All other aspects of the Bemo chassis are the same for the Nm YsteC Ge 4/4 (Crocodile) and the other Ge 4/4s. I can send some photos to demonstrate how it could be done. Please let me know how much it would cost. Thank you.
