Dear Kurfürst

I hope these figures will help:

Based on the map published with Jagdfliegerverbände ...Vol 9/3 (approx.):

Frolow: 48 deg 38 min North; 42 deg 30 min East.
Tusow: 48 deg 40 min North; 43 deg 10 min East

According to Britannica Atlas, 1986 edition:

Frolow is more or less 10 Km North of the present Oblivskaja.

I have been unable to find a town close to the Tusow's position. It is WSW of Kalatsch na Donu ( the name in Britannica for Kalatsch).
There is a large modern reservoir in the region and perhaps the old Tusow is nowadays under the water.

A Russian member would probably be more helpful, but I hope that this could be useful for you.

Regards. Saludos
