Help me identify my Flexaret model

[lynnb]

I'm having difficulty identifying which model Flexaret I own. The Czech TLR site seems to indicate it's more likely to be a IIa, but the Prontor-S shutter to 1/300 first appeared in the III, which had crank winding. The IV went back to knob winding but has a Belar taking lens (mine's a Mirar) and a Prontor-S to 1/400.

I want to replace the mirror but need to identify the model so I can order the correct one.

I'm guessing it was one of the last of the IIa that got a Prontor-S shutter rather than the IIa's regular Metax.

Thanks in advance if you can help.

You might be interested to have a look at the following site which describes the IIa model could also be equipped with a Prontor-S, sadly only in German :

Thanks very much Hans! It looks like mine is a IIa.
