Thanks - that's helpful. Are you getting the director & incorporation from Companies House records? If so I'll get those.
What now looks likely is this timeline:
J W Pickavant leaves the RFC/RAF in June 1918 as a Flight Sergeant Mechanical Engineer/Driver - "chronic bronchitis" as reason for early discharge.
Later in 1918/19 forms J W Pickavant & Co with Wilfrid Hill and Miss M E Baker as Partners. He resumes his pre war occupation which is shown as "Metal Polish Manufacturer" in the Imperial War Museum Records. He also acts as a "Manufacturers Agent" for the County Chemical Company selling products to the early automotive trade.
In June 1921 he, and Miss Baker, join with Marcus and Justin Mindelsohn and J W Pickavant & Co Ltd is registered, with just those 4 as directors.
This must be the point where Wilfrid Hill moves over to County Chemicals in a full time/directorship role - and his career stays with County Chemicals. We suspect that JWP's "Metal Polishing" products & process must have gone to County Chemicals.
In April 1925 JWP emigrates to Canada, leaving the UK company carrying his name behind and in the sole ownership of the Mindelsohn family.
However his association with Wilfrid Hill & The County Chemical Company continues in North America from his base in Toronto. He is known to be still involved selling their products to the North American market, including the freshly invented Brylcreem product in 1928. See clip from his letter to Sykes-Pickavant in 1970.
In this letter he also claims to have been the first importer of a small car to the American continent in 1925.
We've also been able to fact check that by entries in Toronto Trade Directories and by the pic we've located.
The cars in question were from Morris Motors - so quite a big deal.
This venture only lasts a few year and fails costing him around $100,000. However, the World was just heading into the Great Depression.
His success and earnings from County Chemical Products and especially Brylcreem must have been substantial, and he crosses the Atlantic a number of times on White Star ships.
He went on to live a long and prosperous life.
This has taken quite a bit of digging around but I think we've now got a very plausible timeline of events and a very interesting story.
When our project started I had been somewhat dismissive of JWP stereotyping him as a "flash salesman". How wrong I was! I see him now as bit of a hero. From very humble beginnings in Lancashire he survived 3 years on the Western Front, but still came back home very sick. But non of that stopped his pursuit of success.
The connection between the Tools sold by J W Pickavant & Co Ltd and the Chemical products from County Chemicals can be clearly seen with one specific product that was one of the very earliest tools the company sold = Valve Lappers. These are used by the trade with Chemico Grinding Paste (both products are still on sale 100 years later!
