Two loco boilers at Gilfach Ddu in June 1972. This little workshop in what I think was the old loco shed for the Padarn Railway didn't seem to have any obvious connection with the Lake Railway. The nearer boiler with the exotic chimney appears to come from O&K no. 12722 which is now at Bredgar and the farther one is from Hunslet 0-4-0ST "Sybil" which is now at the Brecon Mountain Railway.
