No offence Shaun, but I'm not going to give that out as I don't know you personally....it starts H12*** and has been registered with Flash at the Hetchins register. It's not one of the cheaper ones, or a Bob Jackson one, nicked or fake though!
The original owner had it bought for him on 1979 by his father, after he broke his fathers own frame!
Flash suggested that it could have been a 'special', built for someone but not collected, as the serial dates it earlier, before this bloke turned up looking for two frames....Alf loved doing a deal!
