You feel familiar with this Canon Checkbook Junior calculator? No doubts, it is nothing else than the original Checkbook with two of the three account memories and their respective keys removed.
Dismantling both calculators reveals a small surprise - they are identical. The only difference is the keyplate covering the missing keys from the original Checkbook.
