Vickers-Armstrong / Vickers-Armstrongs Silver ARP Badge

A minor conundrum has cropped up regarding the silver VA A.R.P. badge. There are two companies that use the VA monogram - Vickers-Armstrong (aircraft manufacture) and Vickers-Armstrongs (ship-building). There's a distinct difference between the two as shown from the BAE/Vickers (Aviation Department) Limited website:

Vickers-Armstrong Limited during 1928, Vickers (Aviation Department) Ltd was formed into an official aircraft company under the name Vickers Aviation Limited. This was only temporary however, as months later they became involved in a merger with the heavy engineering (i.e. non-aviation) interests of the Armstrong Whitworth Development Company. A new company emerged as Vickers-Armstrong Ltd, the 's' being removed from the name to differentiate it from Vickers-Armstrongs Ltd, the group's ship building activities in the North of England.
