This is a Royal CBC 95 Solar Checkbook Calculator.  It can track up to 3 different accounts and can be password protected.  It is tested and working. It comes in a red leather checkbook holder with a pen. I purchased this new and never used it.  It has been in storage. It has scuffing on 1” of the edge from storage and a black line on the back. This is a great way to track running balances in multiple accounts. I do not have the instructions but I’m sure you find them online.
