Back in the day when BMC / Leyland cars were being assembled, was it common place for bare metal panels to be written on?
I recently had some panels paint stripped by Sodablast. This is a unique method of paint removal because it does absolutely NOTHING to the metal surface (ie: it is not abrasive). When the paint was removed there were 2 panels that clearly had writing on them. It appears that the panels were written on in a bare metal state.
I am curious to know why this would have been done, and what the markings might mean?
The inside of the drivers door has this on it. It clearly looks like the number 6.
On the passenger side, where the door hinges bolt to the A panel, is the word BUFF, clearly written onto the bare metal shell, most likely when it was progressing down the production line in Zetland, Sydney.
Whatever was used to write these numbers / words seems to have etched the bare metal, leaving this evidence to be discovered 35 years later.
If I sanded by hand, used paint stripper or used some form of grit blasting, this would never have been seen again.
Anyone with some inside knowledge know what this means?
