I can find it right now, but I believe there is mention in the Greener Book of an Albert Greener,a brother/relative of the English(Real) W or WW Greener.
I think he came to the US.But I remember seeing a pic in it of an Albert Greener Hammergun in there somewhere.If I remember right there was a couple of lines on him, but didn't seem to have made many guns...not much info on quality or quantity...but the Hammergun looked alright!
