I am adding a smoke unit to older Locomotive as the original pellet one is missing. 
The picture is from P. 70 of Greenberg's Repair and Operating Manual.
Can a substitute be used? Pondered 3d printing but then again not so
much as around the heating element. I have found the other parts
671-188, 671-189.
Most importantly, Where to find such a part?
Thanks, UnclePeteRR

Don't think I would print it. It takes a pounding. Do you have the piston?
Yes, Bill I have the piston and got it The Train Tender .He looks like he bought out the old
Brasseur supply. This last piece I need. Any Suggestions? Thanks Pete
ps really cool story behind this specific engine and where its headed.

That was obsoleted very quickly, which is too bad as it is a wear item. I have a couple that are worn, when the time comes to address them, I will probably form new ones from flat stock. They won't look the same, but they will work as intended. The problem is to select a material that will hold up for a while but not cut off, or in to, the little nub eccentric on the wheel.
Rob, What kind of metal do you form them out of? When you do, could you make an extra and charge me?
A widow neighbor gave me her late husband's boxes of trains. We all know the drill; rusty track, cheap postwar cars and then a few Finds. I rehabed the postwar inspection station wagon and now the S-2 Turbine. Pete
Rob, Can you post a picture of one yours next to a ruler,please?

As I indicated, I have not done this yet. I am subscribed to using some kind of aluminum when I do get to it, but these are back-burner projects. Whatever I use, I will go with something that is sacrificial to the nub eccentric on the wheel as it's a lot easier to replace the flapper then the wheel.
Maybe I'm way out in left field here as I never saw the actual steam turbine locomotive in action but - the part the poster is looking for makes the smoke unit "puff". Since this is a steam turbine locomotive, I suspect it never "puffed' at all but rather emitted a continuous stream of exhaust smoke as the turbine unit would send a continuous steam output due to the high rotational speeds involved.
That being said, substituting a fan driven smoke unit would cure two problems with one solution.......
