The G-10 we have already runs on 1.98 if I'm not mistaken.
G-10 is being dropped according to Pyro.
Designed or not, there is actually a greater case for a 190 on C3 than any 109.
Designed doesn't mean it ran it, in fact everything points to the conclusion that the primary user of C3 was the 190s, up until as late as March 19 1945.

Shame it isn't all visible, but at least shows -
190 using C3 extensively, only K4 unit visible is on B4. Bearing in mind C3 is required for 1.98ata.
1 day later an order was issued to convert the 3 K4 units to 1.98ata, but nothing has been produced to show this actually happened. Look at the date, the war ended 1.5 months later!!!
