Nope, just got the two now, one to use, one unlit. I've had a few over the years and in terms of burner and simmer control they are the king of meths cooksets, better than my beloved Trangia even; just not as compact and you can't pack a kettle with them.
Base-camp sell the safety pourer and measuring piece (or did).
Chris Townsend commented (IIRC) that you can roll them down a hill without spilling fuel.
The old Gloy's Heatpal use something along the same lines (but not the same)
I've pictures of the Trapper somewhere, if I can find them I'll post if anyone wants to look.
