Hi, I was wondering if anyone could confirm some details (or set me straight) with this one please? It's my mum's knife, given to her by her dad when she was a young girl in the 1950s.
Going by the winged crown logo and made in Germany stamp, the only similar example I could find online was listed as being made by (Friedrich) Olbertz, maybe in the 1940s or 50s?
The knife was quite heavily tarnished as it had been sitting in a drawer unused for years, but a little camellia oil and a bit of time working the tools back and forth and rubbing them with kitchen paper and it's cleaned up somewhat.
It's well patina'd and some of the tools are still quite stiff. My grandad added this pick and chain when he gave mum the knife so that she could open it.
There are some gaps starting from the bail end but I'm a bit reluctant to try tightening it in case I damage it.
It's difficult to know for sure, but I think the covers are bone. They look like black plastic in most lighting conditions, but in very bright light there's a slight translucency and damson-y purple hue and what appear to be pores, and it's a hefty knife for its size.
If anyone could confirm the date of production or maker please I'd be grateful
