OK thanks, the Hague it is.
So, I bought this a couple years back
An Epiphone Rivoli cut down to violin shape, and the sides filled in with mahogany (just an edge about 1cm wide). I'm not a great fan of Violin basses, but it was going cheap. Rather it was relisted a few times on ebay; a little cheaper each time. It had some original parts, and I thought about restoring it, but in the end I just thought i'd use the parts.
Anyway, a few nights back I decided i'd take the pickup out and put it in another Rivoli that has a Dimarzio model 1 in at the moment.
Started unscrewing and found 8 pieces of card underneath - used to adjust the height.
I reassembled the pic (that I assumed to be Holland, and as we now know is the Hague)
And a short message on the back became clear
