Vintage J A Henckels Solingen 3 3/8” Pen Knife 19th C?

Old J.A. Henckels 3 3/8” pen knife with carbon steel blades, brass hafts that once had a cloisonné enamel design. Blade stamps lack ‘Germany’ but do include Solingen which suggests pre 1891 manufacture as Henckels exported a lot to the USA and should have included ‘Germany’ after 1891. The marking of the twins are thinner and more square like the 19th C markings as well. However I cannot verify this, just an educated guess, this could be more recent but the 1960’s is the cut off period for Henckels folders.

Blades have no wiggles, large blade has a stronger snap however, the small one is a tiny bit ‘lazy’ needing a little guidance to close.
