NM. I was reading a section on the Eastern Front, and misread an E for an F. There was a photo with a caption stating ".......ground attack units retained the 'E' variant well into 1943, after other units had long since changed over to the Gustav...."
I also should have read the section breaking down usage of 109s by various other countries besides Germany. It shows Finland received its first 109's in 1943, 28 G-2 models. The remainder were G-6, G-8 and G-10 models, making a grand total of 150 Bf 109's delivered to Finland.
My bad.
