Me too...however the whole EddieLee "thing" had not much to do with Eddie himself, it was his Hong Kong rep disti that had sellection of reps that were a step above the rest, sort of a "mini-Honpo" source, if you get my grip.
Promoter, I'd at least relume dial and hands in Superluminova, upgrade the cannon pin/hour wheel set, and shorten the minute hand tube. While you're at it why not flattening and polishing the cannon pin top.
I'd leave the mov't as is, being square version or E-series version ETA 6497. At least the ETA mov'ts back then were exactly that, an ETA.
Good luck
