I heated one end of the stick cap with the heat gun and gave a pull on the wire lead on that end. The guts slid out without too much effort and the result is below. In the upper right you can just see a dark wire coming out of the tube. This is copper braid that is connected to the common lug in the center. Fortunately it remained in place and connected:

The stick part is a wooden dowel with the foil and insulator wrapped around it. I started unrolling it here:

When I got down to the wooden dowel, there are metal caps on each end with the wire leads soldered into them. I sawed off the caps from the dowel, drilled out the wood (with some picking with a small screw driver) and unsoldered the wires. Two 0.1uF caps were connected to the common copper braid and then longer wire leads were added to each cap. I used some electrical tape and shrink tubing to keep all the connections separated and then stuffed the two caps into the cardboard tube. A bit of swearing, soldering, resoldering, re-resoldering, more swearing and the leads were soldered into the metal caps and then the little wax covered cardboard ends were fitted over the metal caps. One end looks very original, the other..not so much but for the first time I'm happy. Here is the end product:

One more exactly like this and another double 0.02uF cap. Then it will be back to stuffing the more familiar paper tubular caps.
