You'll probably get a better answer if you post this down in the "Curio and Relic" Forum, down a few forums from this one.

The "7A" is probably a partial M/47A, which was the dispersal code for Birmingham Small Arms (BSA), Small Heath, Birmingham plant. BSA produced 25,000 No. 7 Mk. I/L bayonets. "F5" is probably a partial "F5" over "B", which is a viewer's (inspector's) mark. This mark has been documented on No. 7 Mk. I/L bayonets produced at the Royal Ordnance Factory, Poole. ROF Poole produced 30,000 No. 7 Mk. I/L bayonets.
