[What car was this wood steering wheel (?) made to fit?]

Really appreciate the feedback, many thanks!

 

Also wanted to include two OD images of the fingerjoints (if that helps with determining its lineage).

They're on opposite sides of the steering wheel:

Picked up this wood steering wheel (?) a few decades ago, refinished it and it's been hanging up in the shop ever since. 

Always wondered what it came off of.  I've included measurements and made note of an imprinted "K" on the same side as the fastener holes.

 

Thanks for your input!
