And another welcome Davy, this time from the (relative!) fleshpots of Inverness. As luck would have these things, I tried to visit the Firth Cameras website only this afternoon and I see that they have stopped trading. I've popped in there a couple of times when I've visited Orkney in the past and he always seemed to have something interesting, but alas no more!
Yes, sadly the gentleman that ran Firth Cameras passed away a year or two ago.
Thank you for your welcome all the same.
