Tann would be interesting, but I’d be amazed if it was. Although we haven’t seen the lock assembly on Neil’s safe in question, going from past examples of similar appearance I’m convinced it’s going to be as basic as my example I posted. Carron’s were the same, with the crude warded assembly just screwed to the inside of the door.
I’d expect a lot more if it was a Tann, more like the James Gray, Edinburgh example on safeman’s website in the old safe museum section. The lock unit on that ones a beauty- a lot heavier construction and has additional levers to overcome, all made to a very high level of precision for the day. I’d expect a Tann to be more on that level than the examples I’ve encountered. But, I admit we haven’t seen the lock on this one yet…
Thinking about it though, if it was a Tann then I think safeman would have sniffed it from 1000 yards…
PS: safeman posted his reply while I was doing this one, so it might all be a bit out of sync…
