Five old tin register trays which I believe were part of an old McCaskey Register Accounting setup. Your account number and nane were written in and reciepts from your purchases were slipped under the spring clip. When you came in at the end of the month to settle up your account the reciepts were tallyed and you paid your bill. About 3-1/2 x 7-1/4. Nice addition to a General Store collection. (cjcs-1)
