Info on maker of vintage BRW Parlor?

[harrison phipps]

There is no label and only a faint and incomplete stamp on the back joint reinforcing strip that I cannot make out or recognize.  Does anyone recognize the mark?  It is a vintage Brazilian Rosewood parlor, slot head ebony fingerboard and nut, missing original bridge.  It has wide purfling on the top & back. There are 5 back braces and the top was ladder braced with a pin plate across the entire length of the top and two of the top braces at an angle that gets wider towards the bass side.  The side reinforcing patches are rosewood.   I am trying to determine the maker.  Thanks

Harrison, a black light will likely help with the stamp. You can find them new sometimes for under $20.

Harrison, pictures of the front and back of the peghead, the heel, and the back would be helpful.  Any markings on the end of the peghead?
