410M - Stewart-Lundahl Company

Stewart-Lundahl Company, USA (original owner)
1940's-50's?

Ulrich, North Hollywood, California, USA (later owner/commissioning contractor?)

1950's-60's?

See also: Ulrich

Hobby paint (and adhesives etc?), originally designed for wood/metal models, it was lacquer-based and would craze or melt the top surface of styrene models as they gained in popularity. Consequently a new formula was produced for polystyrene kits, a waterproof vinyl coating with an alcohol base, which is said to have been very good, mixing and thinning easily for airbrushing, drying to a fine satin. It was not compatible with its contemporaries though, using its own thinner/cleaner.

By the time they disappeared they seem to have been owned by or re-branded to Ulrich (who had had their own paint range?). I should point out the the Internet will tell you it's 'Ambroid', 'Stewart/Undall' or 'Floquil (410M)', as far as I know Floquil were a separate brand (eventually part of Testors, now withdrawn), Ambroid made (still make) glue (and a range of wooden railway kits) and the Undall thing?...typo!

410M is also the brand/coding for various 3M double-sided bonding tapes!
