Here is a real nice re-production of the original CASE Steering Wheel used from the mid to late 50's on the 200B 300 300B 350 400 400B 500B 600B 700 & 800 CASE Tractors.  This Wheel Measures 17 3/4" Dia. and has the original "flare, or curve in the spokes as they leave the hub. The picture may be distorted some, but these wheels are perfect.  Some wheels we have looked at do not have that "flare" in the spoke and we won't sell them.   7/8" - 1" Tapered Key Shaft.  We also stock the chrome acorn nut if you need it.  Please contact us for all things CASE.  As always, we are happy to combine purchases to save postage.
