"In country" meaning in France or in the USA?
France
It looks like this stamp was applied before the outer shock tower cover was put on the car as the stamp is under the bolt and it doesn't look like the bolt has been removed or replaced?? (there is no evidence of the wear pattern like when you remove a bolt or replace it as these star type bolts usually scratch up the paint.) Was it perhaps an export stamp from the factory denoting the car was for export?? Looks like the first word is "Quality" something. Just my 2 cents.
If you notice the scars from the star washer are different front the star arms. looks like they are off IMHO
Your correct the first word appears to be in English (would end in a "e" if french) though that spelling is correct in Perisan and I'm not aware of which was used in what part of the country in the 60's. The French can be very particular about language
followed by a number and other letters/numbers
Last word looks something like AFP?CAFIB? or AFPACA?D? Not sure if we'll ever figure it out from this picture alone
Have never seen this stamp on another export - even ones going to France - so far.
But other export cars I've seen from NJ going to Europe didn't have this
Looks like I'm wrong about the export as the DSO is appearently Jacksonville. But maybe an export stamp just the same??
Depends IMHO when the car was imported/exported.
