If you look carefully at the butt socket markings the cypher & the '19' of the year date have all been applied together, with the '36' being added later. This is very common on interwar rifles, certainly of BSA mfr. I have a few of their 1930's dated barrelled actions & IIRC they are all marked like so. Waste not want not, I suppose!
