The Meguro Kogaku Melcon is a Japanese 35mm rangefinder camera built in the Leica screw-mount tradition. Produced in limited numbers in the early 1950s, it sat in the same niche as other domestic Leica copies of the period, aimed at photographers seeking a Barnack-style body without importing a German original.

Sales data for the Melcon is extremely thin: a single recorded UK auction hammer result of £650 from 2016 is the only reference point available, so today's value should be treated as indicative rather than settled. With so few examples surfacing in the saleroom, condition, completeness and the presence of an original lens drive most of the price, and a clean working body could realistically sell for more than that figure if it appeared at auction now.
