Camber or castor? Some old posts accidentally interchanged the words!
Apparently the girling radius rods fitted to high frame cars reduce the castor (backward lean of kps). This would suggest 1933 and 1934/5 Ruby radius rods also differ but I dunno. To some extent castor with the pre Girling radius rods is adjustable by twisting. Tend to work themselves into a lesser castor state.
Many advocate at least original and preferably increased castor to reduce wander.
Camber places the turning point on the road relative the kingpin axis extended. For the same angle the lateral location with a very large overall dia tyre is slightly different than with a very small one but hardly significant. I have noticed in photos a definite range of camber angle so possibly the angle incorporated in the stub axles did change at some time. But then when servicing kingpins how many diligently check for squareness?
(In current issue of VSCC LCES magazine two chummies with very different camber! Someone may be able to reproduce if that allowed)
With a vice, 1/2 inch rod. square and level not difficult to compare stub axles.
