That works. You have a round bottom footed kettle. The short feet tend to suggest a piece made to be used either on a hearth, in a wood stove eye, or on top of a wood stove. Although bottom gate marks are seen infrequently after the late 1800s, a smaller foundry might have still been using that technology. It doesn't have that pre-Civil War primitive look, so I'd guess 1870s-90s. Based on other similar pots I've seen, this would be a size #8 (hence the numeral), and the E A the initials of the foundry or the foundryman who made it, probably the latter. Skewed letters imply hasty application, and raised letters would have been formed by making an impression in the inside of the sand mold after the pattern was removed. If they were a part of the pattern, one would assume more care would have been taken in their placement.
Appears to be of good quality, and although I wouldn't necessarily try to find an excuse to cook in it, I don't think there's any cause for concern if you did. I'd probably run it through a lye bath and finish up with electrolysis just to be safer. It doesn't look as it sits now that it was used for anything like melting lead or changing the oil on the car.
