Seems quite an evolutionary step from that agi to Spiralator.
'Real old' Easys have copper tubs. That agi looks that old but not the rest. 46-49 I'd guess. Grandma's 1951 had the spray rinse hole in the spin cover, drain control handle, very similar drain hose (what can be seen of it) including the suds save hole in the wash lid. Aren't the lid knobs missing? Any drawer handle would do.
