Williams C34 Crank Alternatives

Hiya Folks,
I've got a Williams C34 cottered double crankset on a 1953 Holdsworth
.
165mm cranks
48/32 Williams rings
Bayliss Wiley #14 spindle
.
It works but it has a couple of issues:
.
C34 cranks are swaged and the rings do wobble about 1mm
It's a bit too close to the frame
I'm used to 170mm cranks
.
So now I'm wondering if I should try something a bit better quality.
I've also got a hankering to go back to 52/36 rings (52/13 as top gear) or possibly even 52/32 if my rod shifter can handle it.

I've researched previously and the only really obvious candidate I can see was Stronglight 45:

Stronglight 45 "Competition"
.
5 pin
50.4 BCD
Takes TA Cyclotouriste rings (outer 52-40, inner 42-26) - available new from Veloduo
.
Stronglight 55 "Competition" or Stronglight 54 "Standard"
.
3 pin
116 BCD
Stronglight rings are 54-45, but possibly Nervar do a 36
.
1958 Stronglight catalogue:



So my question is can anybody suggest a decent cottered crank I should consider that can handle 52/36 and preferrably also 52/32 ?
