gemmer steering box id?

does anyone what this steering box is from part # 34587 ? it looks very similar to a f1 box just a lager housing . i'm thinking 48-52 f4-6 by looks alone . but cant find any info on that part number . thanks kyle

 

Pics are a big help.

 

It's gemmer.

 

opps ****ty speller

 

any luck with this ID I have the same steeringbox and number, dont know what it is.

 

Isn't the number 34587 just Ford's number for a steering box?
