Wanted to buy: vintage no-hit pitcher signatures
 

I'm hoping that someone on the board can help me with a long term project I have been working on. I am trying to find the signature of every pitcher that threw a no-hitter from 1893 on. The list of pitchers that threw no-hitters is long (over 260 names!), but I have narrowed this down to around 25.

I am actively looking to buy autograph cuts or GPC's for these early vintage no-hit pitchers:

Bill Hawke
Elton Chamberlain
Ed Stein
Jay Hughes
Red Donahue
Walter Thornton
Chick Fraser
Weldon Henley
Harry McIntire
Jake Weimer
Stoney McGlynn
Ed Karger
Johnny Lush
Nick Maddox
Rube Vickers
Leonard (King) Cole
Thomas L. Hughes (Highlanders)
Carl Cashion
Jim Scott (Chicago White Sox)
Frank Allen
Claude Hendrix
Alex (Miles) Main
Arthur (Davie) Davenport
George Mogridge
Don Black (GPC or signed 3 x 5 only)

Thanks in advance for your help!
