We just got some new-old-stock Sugino PX crankarms. These had been hiding in a corner of Sugino's warehouse for many years. When we asked Sugino about making more, they told us the molds had been discarded, but there were still a couple of cases of 175mm arms around.
The Sugino PX was Sugino's version of the TA Cyclotouriste, or Pro-5-Vis crank. Like the TA it uses the great 50.4mm BCD. That means you can use all the TA chainrings, from 26t to 62t. It can be set up as a single, double, triple, or even as a quad. Unlike the TA, there is plenty of room between the arm and the outer chainring so you can use all the modern derailleurs with "shaped" outer cages and it's much easier to fit chain guard and chain cases.
Best of all, the PX arms cost $145, versus $235 for the TA crankarms. 175mm only, JIS spindles (115-118mm for doubles and 120-121mm for triples. Regular British pedal threading.
Also, we have double chain ring bolts for TA or PX cranks again.
UPDATE: I think the q-factor for a double PX is closer to 148-150mm
