Widget wanted

It's a fine evening, and with great foresight I left a few things on board I need at home. So, after work, I caught the bus out to the marina to sit and enjoy a bite to eat at the bar on the waterside.
To while away the time before the bus back I set to on one of those small jobs that didn't make the winter jobs list Some time ago one of the handles on the floorboards broke. No big problem. I'll just swap the broken one for the one on the board with the spare anchor under.
As it happens it was not just a case off screwing it loose and screwing it back again. Strange but true, on the back they are not the same. So now, before I take a chisel to the floor I might as well see if I can get a new one.
Any tips?
