Not sure if these are genuine B&M or not, but there are two wood passenger cars on display in Ithaca, NY..
they have been there since 1970..they are two red coaches, and both have trucks marked "B&M 10495"
Three of the visible trucks say B&M 10495! so clearly 10495 is not a road number..
I believe this coach still has both sets of trucks under it..one set has been enclosed inside the brick platform, which was built as part of the restaurant.
(no longer a restaurant, its now a bank)
More photos, and the rest of the display, can be seen here:
