So I'm building 1/48 Fly models "Roland D VIa" and discover that the resin engine provided with the model is Benz Bz.III (thus for the VIb) instead of the Mercedes D.III engine - I thought it was a little off... Model is also too far along to make it a VIb

I sorta don't want to lose momentum while I wait for customer support. In the meantime ( I could certainly use spare engine in a dio later), I'd like to find US based source of (either one would do):
- Mercedes D.III in 1/48 aftermarket part? Can be fancy.
- Name of a 1/48 kit that has Mercedes D.III as a spares parts (preferably still produced)
- If you have parts for complete 1/48 Mercedes D.III and want to trade
I guess, I could also buy a Weekend Edition Albatros
