I will be able to test this myself when I receive my packages at the end of the week,but what is the length of the Atlas 0-8-0 tender compared to the length of the Bachmann USRA short tender. I am planning on kitbashing a Milwaukee road 2-8-0 & 4-6-0 with the short tender and the narrow coal bunker using the Atlas shell on a Bachmann spectrum USRA short tender frame. Suppose I should have found this out before hunting down and bidding on Atlas shells. (my bad)
I don't know the length off hand, but I did this to replace my 10 wheeler tender. Shell Length is almost identical. You shouldn't have any problem at all.
