I believe OS stands for Optical Stores.

thanks for your answerd, but have you a document about this ? An other personne tell me OS Optical Signals equipment, like ZA for Wireless/detectors/optronic signals equipment or YA for line signals equipment.

Unfortunately I don't have any supporting documentation on hand.

I believe it’s Ordnance Stores.

Isn't the Broad Arrow marking the indicator of Ordnance Stores?.

[WpgBinocular]

The Broad Arrow is in indicator of ownership and is also seen on other non-military government property. OS is a VAOS (Vocabulary of Army Ordnance Stores) coding.

So, then getting back to Daniel's question, is there a document which lists the VAOS codes?
