help identifying a vintage model

[pipetto]

hi everybody,

i"m trying to get info about a vintage model.

i found some details :
- 25 world records
-1937 because letter " o" engraved
- glascow hallmark
- 9 ct gold
-28 mm size

model réf 2008 ,

some questions still there :

- is it a gent model ?
- is it a " prince model " ? -> please see the rolex ad from december 1936 ,

it's difficult or impossible to get info & pics about this 2008 ref ,
is it a rare model ? because on the ad ref 1862 & 1936 are very common on the web

thanks in advance to evrybody.
