I have just found out that Long Rock engine shed was rebuilt to Churchwood's standard straight road design in 1914. I've also found out that the engine sheds re-built during the 1930s, with finances supplied via the Government Loans Act, were, in the main, built with a steel frame, half brick wall topped asbestos claddings and a corrugated iron roof. So as my engine shed is brick with a slate roof it does not fit with historical events.
I'll have to make a slight amendment to my backstory something like; The previous wooden two road engine shed at Penzance would have been moved to a location south of Crowlas during 1906 and build to Churchwood's new brick built Straight Road design. This would provide locomotives for Penzance, Gwinear Road, St. Ives, as well as St. Just and Newlyn. This fits with Leamington Spar and Fishguard sheds being rebuilt in 1906 to Churchwood's standard straight road design which had brick walls under a slate roof..'
As they say, 'you learn something every day'.
