Guest billybird Posted June 24, 2011 Share Posted June 24, 2011 I see a lot of restorations that have duplicated the factory paint/chaulk marks on items such as the firewall, rearend, etc. I'm not agaist it. In fact I think it is impressive. My question is: when did the manufacturers start with these marks? I'm thinking after WWII? Anybody know? Whats the oldest car you have seen with a factory mark on it? Link to comment Share on other sites More sharing options...

Restorer32 Posted June 24, 2011 Share Posted June 24, 2011 I recently looked at an untouched '31 Cadillac V-16 Limo that had several identifying/job numbers lightly stenciled on the firewall under the hood. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted June 24, 2011 Share Posted June 24, 2011 The Egyptians used such marks on their chariots. Old carriages and furniture often have marks in the form of Xs, circles, wavy lines etc to help match up parts where they fit together.Archaeologists recently discovered that the Egyptians built sea going trading ships that were meant to be taken apart and put back together again. No doubt the parts bore some kind of markings. Link to comment Share on other sites More sharing options...
Restorer32 Posted June 24, 2011 Share Posted June 24, 2011 Here's a trivia question for you. If you've ever been in an old barn with hand hewn beams you will notice that the beams are usually numbered with Roman numerals. Obviously they used the numbering system to aid in assembling the various beams etc but why the Roman numerals? I know, does anyone else? Link to comment Share on other sites More sharing options...

But Arabic numerals (mis-named as they actually originated in India) need curved lines. Link to comment Share on other sites More sharing options...

Dave Mellor NJ Posted June 25, 2011 Share Posted June 25, 2011 Roman "C"=100, "D"=500. Both are curved. I guess they don't need the high numbers.While we're talking Roman Numerals, does anyone know if there's a letter for 10,000? 100,000? 1,000,000?

Curti Posted June 25, 2011 Share Posted June 25, 2011 I'll try to get this thread back on track. I have found markings OK & X on 1934-36 Auburn dual ratio rear differentials. I believe these markings originated at Columbia gear. Link to comment Share on other sites More sharing options...

West Peterson Posted June 25, 2011 Share Posted June 25, 2011 I guess it's safe to say that it started well before WWII.When I took the dog-house apart on my 1940 Packard, inside was the hand-written marking "Sup 8 A/C", meaning Super 8 with air-conditioning. Just to make sure someone installed the condenser before installing the radiator. Link to comment Share on other sites More sharing options...
Seldenguy Posted June 25, 2011 Share Posted June 25, 2011 A few years back I had a seat that came off an original 1907 Buick roadster. There were chalk/paint marks on the bottom that you could see after it was separated from the the main body. As I recall it was marked Job # and two digits.It was also raw wood on the bottom, no paint.--Bob Link to comment Share on other sites More sharing options...
