Rod - hello. Just noticed your 7 July post. What's the basic stamp (i.e pre-overprint), please? I came across a couple of these recently.
Geoff,
Just so you know, just in case you think I know off hand, and have instant recall......not a bit of it.
I went looking in Saudia Arabia first

I found it, along with my memory, as a Turkish Fiscal, for sealing cigarettes
I'll do some more research and post back if / when I find it.

Update.
I remember now, I had that stamp with a triangle Pmk / Opt
Our dear friend Nigel advised us it was use in Arabia ?
Now I've forgotten that.
