EMELOID TRANSMISSION LINE CALCULATOR This is the improved 1944 version - original was developed by PH Smith (Bell Labs) in 1939. To my non-expert eye the calculator appears to be in excellent condition. It belonged to my uncle who worked for Marconi. He was seconded to RCA in Camden, New Jersey in the 1940s, which is where he will have acquired the calculator. Included in the auction is a reprint of Phillip H. Smith's paper from Electronics January 1944, in which he describes the calculator and it's use. The document is in excellent condition for it's age. Paper is yellowed and there are rust marks around the staples, but it has been kept flat and is 100% readable. Happy to ship to any collector, worldwide. Thank you for looking.
