Mackal in his 1996 LPS article mentions a number of names in connection with the forgers of the first issues
Forger #2 (Spiro) he mentions Zechmayer
Forger #4 he mentions Ventwring
Forger #6 he mentions Sartori, Behrman, Wkras
Forger #19 he mentions Paris
Some cursory internet searching fails to find any existence of these people (except Zechmeyer)
Anyone know anything about any of them?
