purchased recently from a British collector who advised that these were manufactured from aircraft alloy DURING WW 2

The item looks "new" but had been part of an entire box full that was unsold stock from an old toy store that closed down in the 1950's

You will never find an example in better condition and would never need to "upgrade" this once it in your collection

Action is as "good as new" (IE very weak and made without any kind of spring-assistance)
