So a had a chat with a old lady (90+) she and her past away hubby where Importers here in Sweden for Straight razors and mainly from Solingen. thay also had a honing/sharpening service for razors and sugical instruments.
when thay made there trips out to Solingen back in the old days thay went to the big razor factory owned by H.Eicker / maker of Heartring,PAX,Biedermeier etc. when thay went there for business the VD gave them a very cool framed "from the beginning to the end" with how thay made the Heartring 150 razor step by step. as a friendly gesture and as a valued customer.
Since her hubby past away 4 years ago and shes close to 100 she wanted to sell it to someone who will love it for what it is. and so am i the lucky owner of it now. i really love it. its very cool and a big + is im a sucker for Heartring razors.
