Can anyone identify these Darby Cuffs?

Can anyone identify these Darby Adjustable Cuffs that were on EBay? They look slightly slimer than Hiatt and don't appear to be RCS, etc.

Does anyone know the source for a key?

Thanks

Possibly German.

On picture #4 the tip of the bow appears to be rounded, so most probably these are a pair of Kayser No. 7.

Best,

I also think they are German, and probably Kayser as Michael has suggested.

I'm sure Ian McColl would be able to make you a key, but they would most likely require a trip to Australia to have one made.

You can find Ian's details on the links page.

The cuff are Kayser but they are slightly smaller than the plated item I have, while they were out here to have a key made, I forgot to take a photo of the side by side.

The thread on my cuff is 20TPI and this pair is approx 14 TPI
