Leavitt Machine, "Boston, Mass., Feb. 2 .76", Type A1-2 test strike without killer cancels 1¢ postal card (UX5) to Portland Me., Very Fine and choice. Estimate $750 - 1,000.
ONE OF ONLY TWO RECORDED TEST STRIKES WITHOUT KILLER.
A second type of machine, with a mechanical feed but able to cancel only postal cards, was used from early February 1876 to the middle of April 1878. Despite its limited application, the machine met substantial need, since the availability of postal cards in sheets increased their commercial use. A test of the machine was made on February 2, 1876 without the killer as it had not been received at the time of the test.
