TSR's Buck Rogers XXVC game had a good number of supplements and modules. When trying to get a simple list of products and matching them to images of the covers I came across something interesting. From what I can see the Adventure called Deimos Mandate has both XXVCA3 AND XXVCS1 product codes. Is that correct? Any idea why it panned out that way if it is?
The two images below are from the module. The first image is from the produced book that was on the shelves. The 2nd image is from a 1991 product catalog and has the different number. If the firs image is what was final, then that means there never was a XXVCS1, or at least XXVCA3 is the same thing. The 'S' line started with XXVCS2.
