The idea of a brief checklist for your very gracious - but still a non-bike hobbyist - lady friend is a good idea. As you can see though by the serious-bike-guys' suggestions here it can and will very quickly become way too cumbersome for a volunteer to be bothered with. Starts to look like a House of Representatives Bill loaded with Amendments. You've already caused a floor debate over cotters and one-piece cranks.

Might be a good thing for every one of us who goes junking for bikes to make up a simple list with our own personal preferences and keep a copy or two in the car in case a good volunteer candidate comes along. Every person's list will be different. BTW, to a non-bike person a filthy and scratched 1970s bike looks the same as a 1950s bike and I wouldn't expect such a volunteer after two months to remember lugging or fillet brazing much less dropouts.

Simple and brief, not to mention some sort of thank-you gift just to keep your credit good with the volunteer.
