Can anyone give me an idea when the Theoben Prometheus was being produced? I've Googled my way through an entire pot of tea now and whilst I've found several excellent manafacturing timelines / histories posted on other forums the Prometheus seems to be absent from those lists.
Also, if you have one, does it have a serial number? And if so where is it? I do have a number beginning TB under the barrel block, but it appears to be hand etched rather than machine stamped?
(I shall await a slightly stunned / bewildered call from Dad now who didn't know this one was on the cards...)

Ta folks!
