Good Day,

I was hoping you could shed some light or point me in the right direction ~ I've been researching a product/company. The "Red Diamond" tool company but fear they are no longer in business. My father has a push type lawn mower. The original signage/stamp is visable but one number within the year is difficult to decipher. On the front of the wooden handle, it reads "Red Diamond" quality tools since.....either 1675? or 1875?

Any info on the company, products or possible time period would be appreciated.

Thank you in advance for your time and correspondance.
