Antique Tuckers Alarm Till Under Counter Wooden Drawer Cash Register USA #503. Measures about 18" x 16" x 4.5. Made by Tucker & Dorsey Mfg Co.
Overall in good condition, it is currently stuck open, I believe the metal fingers (see last picture) can be put into the lock mechanism to set password. Please see pictures for details on condition.
