Fatman: What a fabulous set !! Thank you for your discussion on the Brimtoy / Marx potential connection. If the connection is via the motor components, then it is also a potential US connection as well since all the motors for British Marx were manufactured in the US - at least the electric ones, I am less sure of the clockwork.
I especially liked what appears to be a coupling between the coaches that appears to have a simulated vestibule. This makes for a very realistic consist and really looks sharp!
Thanks again for posting.
