Looking at it in 500x I can just make out the UEF over the GHD.
Not sure, but believe in the middle of the wrist you can make out the circular ghost of a Underwood CC.
Stock had to be sanded, to remove the splinters......... After someone put the Power Washer to it. Look at how it blew the grain open !
I agree with Del, that it is a RMC stock.
QHMC CC added to fill someones needs at the time, Shame.

PS: May be remnant of Circled P on grip bottom, unless Washed/sanded away.
