I used the 66 mm pressure bar to repair a WWII vintage Italian Duofold copy. The repair process was exactly the same as a button filling Duofold and the pressure bar was a perfect fit.

Pressure bars 66 mm
My order was promptly filled and the items ordered were received in good order.. However, the bars were of relatively poor quality and, in particular, the 66 mm bars were too wide and had to be crimped to be inserted with the resulting impaired function.
