Did I miss any? These things have got to be the redhaired foster child of N scale having been shifted around to so many different parents. Anyway, I have worked through my stash of these and I now find myself in dire need of the medium length T shank couplers. Thus far I have only found the body mounts and the long T shank couplers. The mediums and shorts are missing. I'll not post the places I checked to avoid running afoul of Trainboard rules about mentioning venders but if anyone knows where some are hiding would you please PM me?
Thanks to all who responded. I was able to replenish my stash by ordering direct from Fox Valley. Why I didn't think of that in the first place I don't know but all is well that ends well. Getting old is not fun but it sure beats the alternative.
