Remember this from 2013? You’re in the thread @miamivice
Ken Wain (author of my excellent book) quotes it as Silkstone and yes it is also the name of one of the seams. Although granted, on later maps it does start to bear the name Swallow’s Colliery. Maybe so as not to confuse it with the seam, or other collieries of the same name?
I’ll keep looking. It keeps me off the streets and nothing doing on the plot this time of year. Next time you’re there and see the car on, feel free to pop down for a cuppa and a natter about this. 😁👍
