well over a year ago my M TH Challenger's front motors gear was badly damaged
I did ask M T H's rep here in England and the main M T H over the big pond but No out of date not made etc etc was the reply
2 friends Mark Harley and John Mallard both offered to see if they could lend a hand in repairing the Challenger and between them they have helped me repair the Challenger
John had a word with a young man at Sommerfelds Trains & Hobbies who did find me the right motor with the gear included for the front wheel unit or what ever you might call it and Mark sent me a front wheel set I hope you can see her running in our front room not long after the rebuild

but that is what I was told on there Facebook site
I did think it was going to be nearly a No go my self once M T H said that there were none around and it could be a two year wait from China for the motor
