This
EC-425 distributed by Radio Shack (A Tandy corporation company) could be easily
identified as a restyled SR-10. The
LED display vary from calculator to calculator, this one uses a Bowmar Optostic.
The mold of the housing looks very similar to other restyled Wedge area calculators like the Montgomery Ward P200.
