Hi, I also have one of these flame guns, I will upload pictures later, the transfer on mine is fairly good, and gives ‘The Haulk Flame Gun Co, Wisbech, Cambridgeshire’ at the bottom, they used to have premises in the Market Place backing onto the River Nene on North Brink.
I purchased mine 12+ years ago from a farm sale at Sutton Bridge, Lincs.
Hope this is some help!
Adam.
