Bashing A Brass USRA 0-8-0

[Schraddel]

Hello,

i have a problem.
When looking to prototype photos of USRA 0-8-0's i was missing on the model the "seam" between both cylinder blocks.
I try to model this seam between the two cylinder blocks and i am not quite happy with my first attempt to do it:

:?
Has anybody an idea?
