John Lord

just found u guys. it looks interesting. do u do any sci/tech subjects? years ago i found several pencil and ink sketches made by Walter Strowger of his original dialing mechanism and an other rotary switch. signed, dated.is there any interest in this period or have cell phones eclipsed all things telephone? also I found an early light bulb, filament intact, internal screw thread base, apparently came out about 2 years after edisons according to a collectors group on line.
