First use of Philips screws and Pozidriv in United Kingdom

[Stephen-in-hull]

I'm trying to date a piece of occasional furniture that I bought recently, and I'm restoring. It's a little sewing box/occasional table, oyster shaped, with a swiveling, opening to double size table top.

The body of the box is formed (literally) of mahogany six-ply, with an oak veneer. The four beech legs are screwed on with Philips screws. There's an old fashioned six colour decal (transfer) on the back with "A MORCO PRODUCT Registered trade mark" around a device of a lady in a crinolinre dress and high wig.

Stylistically, it's pretty timeless, but I rather think 1950s, possibly as early as just post war. Someone told me that Philips screws came into Britain via the USA during the war. Is that so?

I seem to remember Pozidriv coming into use in the early 1970s.

That raises another thought: when did Nylok locking nuts come into use?

Any thoughts, please?

Interesting that the American site doesn't mention the Pozidriv or its later improved version the Supadriv (note the lack of an "e" at the end) which aooeared late 1970s.

I can remember seeing Nylocs in the 1970s when they were quite expensive
