Not sure if this will be popular, but i'd love to see a range of new 1/48 Mercedes D.III engines (D.III, D.IIIa, D.IIIau, etc). These were very common engines and there are no after-market items available or in production. I can only imagine that they would be a good seller for us 1/48 types. I have your Mercedes D.I engine (now also out of production) and I can only drool at what might be possible if you turned your attention here.
Just my humble request
Cheers,
Brad
