Mint Lehmann “Primus” pocket calculator or abacus in box

These were among the first items produced after WWII by Lehmann while under Soviet occupation. Made from 1946-49 the “rechengerat” (computing device) was an item for practical use as well as a toy. Reportedly these were sold almost exclusively to the Soviet army. This one is mint in box with the original packing cardboard along with the blade stamped “Lehmann” that is almost always missing. It is designated EPL 840.
