Can anybody recognize this connector?

[saronno]

Some time ago I bought on ebay a little job lot ... amid other things,
there are some cables I can't recognize.

They are like ..

unknown connector (UC)

UC <-> serial
UC <-> parallel
UC <-> printer port
UC <-> USB

Anyone?

They look like thunderbolt but they are not (thunderbolt has more pin and the connector is smaller).

Something in the picture to give scale would help (like a ruler/measure*) and a couple of views from other angles might help.

*Not coins or other things that aren't internationally universal, I have no idea what size a US penny is, or a 10 Yen piece, just as I'm sure the people who put those into pictures for scale haven't a clue how big a UK 5p piece or a threepenny bit is.

the shield of the connector is 9,5 mm x 4,3 mm
