In your picture it is hard to see the E center foot but it has a big serif on the center foot of the E. The easier one yo see is the=on the depth is more to top right of the A while the "pre comex logo dial" the=is more to the left of the A. Also a little hard to see the Comex and the Pre comex logo dial the lume plots touch the minute markers.
Yours looks to be a great example.
