ZFR-4 and the 109F?

[pstrany]

Hi;

One of the models of the 109F I am doing has a ZFR-4 telescopic sight mounted in the right-hand side of the windscreen. I guess this installation would be similar to the installation on the 109E, as the canopies are (laregly) the same, but would this installation have necessitated moving the Revi sight, or was there enough room on the right side to cram that sight in there? Also, was this just a straight telescopic site, that is, no cross-hairs or any such thing?

If anyone has any pictures of this installation, espcially from the pilot's point of view, I would be extremely grateful for a copy or at leave a direction to look for same.

Thanks!!
