Hi all!

Quick question, haven't been able to find the answer. Roughly how many
GA piston Lycomings have been built? Within a few hundred thousand, at
least, but the number doesn't have to be exact. I'd like to compare
how many were made versus how many wankel rotary engines, just as a
data point.

Thanks!
