Lot of three vintage manuals and guides for getting an amateur radio operator's transmission license. These are from the estate of a radio ham and short wave equipment buff. There are:
The Radio Amateur Newcomer - A Complete Manual for the Beginner in Amateur Radio - copyright 1949 with 160 pages with lots of illustration, schematics and diagrams. The cover is loose and there is some soil, wrinkling and water staining from many year in an attic.
Learning the Radiotelegraph Code - Basic Training for Radio Operating - copyright 1970 with 48 pages. This has some wear and pen and pencil markings.
AMECO - Radio Amateur Question and Answer License Guide - copyright 1973 (1977 printing) with 64 pages. This has wear and soil.
