Oakes Spare Tire Wheel Lock on 2040-parts.com

Oakes cast iron spare tire wheel lock WITH lock and key. Markings are:
Main housing: “B(?might be 8)10777” with what might be a “7” on the second line, far right.
Sliding part: “B(?might be 8)10778”
The lock reads “Oakes / Indianapolis” and uses a Yale key “OC431”

Date of manufacture is unknown but my Dad had this back in the 60's, so it pre-dates that. Housing has a few scratches and appears to have been painted over. This was all done before my Dad owned it.

I was told it was for a Jaguar Mk IV drophead coupe, which my Dad had, but the Mk IV spare is stored internally and already locked. One user on a Jaguar forum opined it was a ca. 1930 Franklin or similar era car.

The lock works, has one key, and its dimensions (max) are as follows:
Length: 5.25” (133mm)
Width: 2.25” (57mm)
Height: 3.75” (95mm)
Weight: 3” 6oz (1.5kg)

Shipping will be paid by buyer, shipped by USPS insured Priority TBD based on buyer's location. Shipping cost will be actual, no added charges. Tire lock is in southeast Georgia. Payment through Paypal goods and services only.
