Looks like an Eaton Gov-lok. Not sure what series. The govener on these units are week and tend to break ( If abused ). I had one and mine broke. ( And there's no replacement parts available )
Someone else may have more & beter info for you.

That unit looks to me , identical to the same used in military m-1008 pick ups. The military chevrolet version . Probably is an eaton as mentioned by Gary.

10 bolt Gov-Lock.............junk in anything with more than stock horsepower or larger tires, many cant even deal with stock stuff.
