Made to order from a black worsted serge cloth sourced from a mill near Bradford. As with my overalls the Firing jacket is copied exactly to be as the original. Coveted in B.R. days a passed cleaner had to complete over 300 turns before being issued with one - hence the status that is associated with these today. Please note, this jacket was issued to keep the wearer warm whilst not actually firing. This item is made to order, and can take several weeks or even months from date of order. Allow plenty of time, and please be patient. Please refer to the self measuring chart on how to measure your correct size.
