Subject: electrical ceramics references?

May 24, 2016
Hi All,
I’ve got a porcelain item with the G in box shown by Lehner 1998:584  [Grabler Mfg Co; Cleveland, Ohio).  She gives no dates, but searching in google books there are references to court cases circa 1910...  Good enough for my purposes at the moment.
HOWEVER, is there a good reference on utilitarian ceramics marks y’all have discovered?  My dear old Lehner is nearly a couple decades old now...
Thanks,
S. Walter
