Vari-Speed Governor Model 149 - Application?

I have a King-Seeley Handy "Vari-Speed" Governor - Model V6 149. I saw one on eBay but it was for a 6 Cyl 216 or 235. Is this for the same size engine? Here's some quality photos of the Guv-nah'!!!











Thank you for any information... it's greatly appreciated.

 

Actually it can be used on any engine that uses that carb bolt spacing as they are adjustable. Thats what the wire and lead seal are used for,locking the adjustment after it has been made.

 

Thank you, John!!!

 

If that "3 44" is a date, it could be military,,,and set to about 45 mph....
