Simpler parts can be fabricated, you know. Some raw material (like brass), some patience and time - things can be made. It depends.
Thanks. I checked everything. I'm thinking of just going with the MTH Yellowstone part of the same type. It isn't shaped quite the same, but it can't be THAT different considering they're both scale reproductions of the same proto-type. Worth a shot for $6 I think.
