Montgomery Ward P300 aka TXI-8663A could easily identified as a close relative of the SR-10.
Both calculators use the same electronics, the same layout of the keyboard and even an identical mold for the housing bottom. The different look is achieved through a new mold for the upper half of the housing and a different color of the function keys. The color of the housing is slightly different, too.
Compare it with it's sibling P200 and another SR-10 clone, the Radio Shack EC-425. If you are looking for a SR-10 with blue function keys, don't miss this SR-10 Rebuilt.
Don't miss the rare TXI-8661A based on the Exactra 23 calculator.
