1930's? Monte Pearson

I picked this one up awhile back. Wondering if anyone has any guesses as to the maker. It's stamped G195 Professional Model, Genuine Horsehide with the Monte Pearson sig. on the heel, but has no stamping as to the maker. I spent more time cleaning this one than any other glove I have. It was almost black and I honestly wonder if it had been lodged in a chimney for many years. Underneath all the grime was some very dry but decent leather and (arghh!) marker on the back and wrist strap. Still, it's well made. Any ideas?
