I agree with Mike, first half 20th century.
I've seen their [HA] [EA] [FA] mark used without the logo above it on older pieces. This is only my opinion but that logo looks 20th century to me. In case you were wondering what the [HA] [EA] and [FA] marks stand for, they are the initials of henry's three sons who took over the company after his death: Henry Jr., Edward and Frank.
