Looks Like Vulcan was a builder.
In the early English days, there were makers and builders. Makers made bikes from scratch and builders bought parts and assembled their bikes. Bike makers and parts makers both supplied bare frames to builders. The biggest frame suppliers were Hercules, Philips and Armstrong.
Yours looks like a Hercules frame from the late 30s, early 40s but could have gone all the way through the 40s. The rear facing dropouts and rear fork are tell-tales.
When you get it, the rear hub marking will tell more. Hopefully a date.
👍
