[Central-Electronics] CE 20A Serial Number

[Paul Christensen]

I recently acquired a 20A with a S/N in the 2600+ range.  Anyone know where
this unit falls in the 20A production life cycle?  Would the mods in the
change notices have been installed at the CE factory - or supplied in the
kits during this period?   I plan on a visual check in the coming weeks but
thought I would ask ahead of that inspection.  Thanks!
