Found at the old site of the Jenny Lind Brickworks, Motherwell adjacent to the old Ravenscraig Steelworks site.

Spinella was a trademark of General Refractories (GR) and manufactured at their Worksop Works. When GR and John G Stein and Co amalgamated (GR-S) it is likely that Spinella bricks continued to be manufactured at Worksop but it is possible that manufacture was switched to the GR-S Manuel Works, Linlithgow to suit demand but this would have meant production plant modification. (For research but in the meantime, I will record them on my website due to the brand connection with a Scottish manufacturer).

I have found a reference to GR-Stein Refractories, Bonnybridge, Scotland selling Spinella MCA  bricks – Spinella being a Chrome – Magnesite brand brick … see example products on 1977 – 1979 sales invoices. It may be of course that such bricks were ordered from Worksop.
