Does anyone know the policy used by BOAC in selecting the markings (engraving) used on BOAC equipment.
For example 131/83/xxx Where I believe xxx is the serial number.
I am more interested on what is on instruments etc but any general information on the subject will be most welcome.

Had a thought that the numbers used in your example of 131/83/XXX may have comtained the ATA chapter in there, 83 is Accessary Gear Boxes which doesnt seem right for a watch. Instruments are 31.

I was meaning equipment fitted to aircraft.
The example above is actually from a watch issued by BOAC, and yes it does have BOAC before the marking I have described.
I however have seen other items before that are BOAC marked and wondered what the logic of the numbering was.

Do you mean aircraft fitted equipment or ground equipment?
For aircraft parts most of the parent workshops had a register from where new serial numbers were taken, usually prefixed BOA or BOAC. Mostly issued when a part that had not previously had a s/n needed one, such as following modification or needing tracking after becoming a lifed part for example. Sometimes also used when a part had lost its s/n but I would suggest that that was rare.
Most significant components would use the s/n issued by the original manufacturer using their s/n sequence.
