Peter,

I'll be honest, I simply do not remember. But with the similar caps I usually see if they are:

1. Paper cartridge without aluminum shell. These often have a very hard substance (would not call it tar) on top. I chiesel out the top part until I get to the innard, then heat it up with a Milwaukee gun and use corkscrew to gut it. Sealing is brown hot glue.
PS> sometimes tthe paper is thin, and not really guttable. This doe snot happen often. I remember making a label for a Zenith Transoceanic cap and wrapping it around a improvised paper cartridge made out of a piece of some thin dense paper.
2. Aluminum cartridge inside. These are better. The top is typically black tar, and I simply pit the corkscrew in and try to heat it up and pull all out at once. Then clean, restuff and reseal with the same brown hot glue.
