Birmingham Screwdriver

Monday morning deep in The Forest of Dean, and Eric & Ernie check over unreliable 13 which has appeared to make a new squeaky grinding sound in addition to the other 23 squeaky grinding sounds. Things should be okay after a few tweaks with Ernie’s new Birmingham screwdriver. He has quite a collection from bull nosed through to sledge, the latter being his choice of tool today - it also being his latest precision instrument.
