WORKING Tested Vintage Monroe K-Series Mechanical Calculating Machine:
$350.00
Vintage Monroe K-Series mechanical calculating machine that has been tested and is in working condition. This classic piece of consumer electronics is a rare find for collectors of vintage calculators and electronics. With its retro design and functionality, this Monroe calculator offers a glimpse into the past and adds a touch of nostalgia to any collection. Very similar to the Smithsonian listed k-series, but can’t say for sure because I can’t locate the serial number. Very cool piece of history in working condition. Don’t miss out!
