The H H probably stands for Harold Hess as he once owned the William Morgan molds. They later went to Jerry DeVuidralle (not sure of spelling). Harold Hess may have assembled that lock since it is marked with his initials.
You might be right here.Harold Hess gained control over a number of moulds including
the Chet Shoults Ketland as well as the Russ Hamm Maslin plus others.He was also known
to sell parts made from moulds that were supposed to be exclusive to anyone who wanted them.
The Maslin lock moulds were paid for by Bill Large and everyone but Bill got parts from them.There was
not a lot of money involved and Bill was not really mad about it.Jerry Devaudreuil got most if not all
of the moulds after Hess passed away and after a long run sold them to a shop in Pennsylvania and
later had to repossess them for non payment.I have heard that Jerry is in bad shape now and no word
about all these moulds he owns.I hope someone will get them and maybe continue selling these pne
of a kind parts.I no longer need them but they shouldn't go to a landfill either/
