Diameter of wooden Chevrolet steering wheel?

Thanks Phil,

Now we need someone to measure up a GMC steering wheel - I think those are slightly larger.

Hi Hanno

If nobody turns one upto measure sooner, I'll look at are big rally July 23rd to 25th pretty sure there will be a CCKW with wood steering wheel there. But now to widen the question, is the wheel used on a DUKW which if I remember correctly were even larger.

Cheers Phil

The 18" diameter wheel is CMP. The DUKW wheel is 20" diameter. The CCKW I cannot confirm at the moment but the wood rim wheel may be the same as DUKW as I measured a moulded CCKW wheel as being 20" outside.

Thanks for the replies.

Meanwhile I found more info on the cckw.org forum including a CCKW steering wheel with tape measure and a link to a helpful French webpage: http://thierry.becker.free.fr/VolantsGMC.htm

The wheel pictured with the tape measure across it is a 4th type CCKW wheel which was used on late production vehicles.
As far as I know the only difference between this steering wheel and that used on the DUKW is the DUKW wheel has a pair of round headed nails driven into the rim not far apart to give the driver some indication of the straight ahead position when afloat.
