Flexaret Lens Cap

[Michael L.]

Unthinkingly, I recently bought a lens cap for my spare Flexaret Standard TLR on *Bay without first checking whether it would match the camera. In the listing photo it looked exactly like the cap on my regular Flexaret Standard, but it turned out to be a much smaller version (approx. 10 per cent smaller) that doesn't fit the lenses.
I'd like to offer the lens cap for sale or trade, but to do this I must be able to tell potential buyers which Flexaret model(s) the cap is meant for; otherwise they could risk repeating my own mistake.
Models VI, Standard and VII can be eliminated, as they all have identical lenses, but I'd be very grateful if some knowledgeable forum member could tell me which earlier Flexaret model(s) the lens cap would fit.
Please see the below pictures for details.
Looking forward to your help,
Michael

The dimension that is missing on your drawing is the vertical center to center distance. You can't know for sure 100% what it would fit w/o that.

Thanks, momus. I know I am a poor draughtsman. The center to center distance is 44 mm.

If it fits the Flexerat III, I would like to buy it but I won't be able to measure mine until tomorrow.

PM sent.

OptiKen has kindly taken the measurements of his Flexaret III, but the lens cap doesn't fit that model either.
That seems to leave the I, II, IV and V. Any information will be appreciated.

It's in the drawing. You just need to do a tiny bit of calculating.
