Terry's a good man to help you with this project!!
I think that you are talking about two different antennas offered from Philco.
The Philco All Wave Antenna Kit consisted of a long roll of a conductor (your antenna), some insulators, and a lightning arrestor. You can make one of these yourself.
The Philco High Efficiency Aerial was included with Philco sets, I believe, in 1937. It is a pretty good antenna for it's size. But as Terry stated, higher and longer is better.
Impedence matching is not really a big deal for a recieving station. It is a big deal with a transmitting station. Since all of your sets are recievers, don't worry about this.
A twisted pair for the lead going from your antenna to your radio would simply be a grounded wire twisted around your antenna lead. In my opinion this is of minimal value for most recievers. A doublet antenna is similar looking but for your purposes a single longwire antenna will offer you great reception.
