Not having had much to do with Top Secret when it was around, after I posted my first response I decided to do a little poking around to find out more about the module you mentioned. There's an interesting page on RPG.net that might be of use to you

However after reading that page and a few other reviews about Top Secret module 001, I even more strongly agree with you about adding those elements to the Free City of Krakow module
