Just been looking at this again, cleaning wise maybe just a little wd40 to remove surface rust, the springs work really well and maybe pick up a lanyard, seen some on ebay and a local anchor supplies military surplus stock.
The maker is actually J Rodgers and Sons not 'Robinson', it might be difficult to read though? The other giveaway about the maker without seeing the name is the Maltese Cross and Star, it's Joseph Rodgers trademark.
Some of mine are here... British Naval Jack Knives including some Joseph Rodgers ones like yours.
Ahh thanks, most of it is rubbed away. thanks again.
I was issued one of these when I joined the navy in 1965. It now resides in Portsmouth dockyard where I dropped it overboard at South Railway Jetty in 1966. I have a replacement now but I still have to stamp my name in the panel on the side.
was that mandatory.
The stamping of name or the dropping,
We brits are notorious theives so putting your name on was essential.
Nice bunch of knives
