Most definitely although they are hard to find now. The best ones don't have the Metric revision tag on the bottom. They have either nothing or "Revised edition" on the bottom.
Main differences are the later version only carries tapping sizes for BA, no thread data etc and some of the other charts have been thinned down. -- Regards,

Why does any Model Engineer need BA thread info ? Do you actually reproduce BA threads on your lathe ??? Hard to believe when tapping drills vary from 1.06 to 5.10 millimeters.

Just today I have used the BA thread data contained in my WWII version of Zeus for 10BA and 6BA threads. TPI and core dia. are very useful bits of info.
