Mechanical Coin Bank Rocket to the Moon

Hello All,
In inherited this cool metal mechanical coin bank. Rocket to the moon. Has a worn out sticker from Lynwood Savings and Loan Association.
Maybe a giveaway from the bank? In good working order. But I no longer have a key to open the bottom where the coins are.

Any thoughts about the year? Any one else have one?

Thanks for your input.

Don
