This was some footage that I filmed inside the Bo'ness and Kinneil railway's Romney workshop in the 90's at my local heritage railway, back in the 1990's when the Bo'ness and Kinneil Railway Locomotive steam guys were restoring Caledonian Railway, 439 Class No.419.
Please love these guys and give them a big thumbs up.
On this video :
1) Welding the Westinghouse air pump on locomotive CR419 (55189) which suffered serious frost damage many decades ago.

3) Various No.419 parts being machined on the Webster and Bennett vertical borer.
4) Rust and cleaning of No.419 parts.
