7A18 option1?

Dave Seiter
 

If my poor brain recalls correctly, the 7A18 option 1 is the same as 7A18N, except that the "N" version does not have trace ID, while the option 1 does, does that sound correct?  I have both as projects with missing parts, and I'm wondering if I should just focus on the option 1 unit. (they are almost identical; the only differences I can see are the pot assemblies and two resistors)
