Lebanon County T-1 (cloth back)

The Lebanon County T-UA and T-UB (both plastic back)

In 1977, National issued the Lebanon T-U CSP as an "official" reproduction of the original. The easiest way to determine the original from the reproduction is the plastic back, which the original did not have. There are two varieties if the reproduction. The T-UA with the "thin" FDL, and the T-UB with the thick FDL.
