This is my most recent 249 which was given to me as a gift. It seemed to be all original except for a brand new generator and pump leather. The burner cap was unusable and there was a crack in the fount at the filler bung. I have run out of spare burner caps so used one from a gas lamp and sil-brazed it to a burner tube with damaged threads. I also sil-brazed the crack in the fount.
Thank you Andrew, well done, how can you know the year of fabrication. I just bought one and I would like to know
Hi @Leonardo Collares have a look at either side of the lower writing for some letter stamps? The 3 signifies the 3rd month (I hope) (thanks to Jakov for the image) hope that helps regards pb
