unknown dash clock-please help identify

recently i bought an old dash clock at a garage sale, and i have no clue what it is from, all i know is i think it's cool. i don't know how to identify it. i know if there is any chance of me being able to identify it it is the hamb!

ok, to start there are a few names and numbers marked on it.they are as follows

on the housing (which seems to be cast of pot metal)
the number- 554054-5-6
the name- Geriti

on the clock it's self
it has the date- may 49 -printed on it
the number- H2282655
it also says manufactured by the Geo. w. Borg corporation, Chicago, U.S.A.

all of this leads me to believe it is for a 49 chevy (or other gm) but i have no idea, can anyone verify for me what this clock is from?
thanks, all help is appreciated!

 

49 or 50 Olds

 

I think 51 and 52 also had a clock like that.

 

thank you very much, the HAMB kicks serious ass! lol

 

I got one on my desk from a 52 chev thats close but not it. An early 50's Olds sounds right.

 

i have one that looks like it mine came from a 1952 olds 98

 

Definatly Olds

 

hmm... guess i did good for $2 then.
