My '73 1800ES is an automatic, so I'm not positive this info will be of any help. In any case, I took photos of both sides of the key and the console compartment itself, hopefully it will match at least one of yours.
The stamped number on the key (which you can pretty well make out in the photo) is VS417. I assume this is the number that identifies the pattern on my particular key. Between that number and the keyring hole are two imprinted entries that were part of the blank - the top line is simply "VOLVO", then a second line, which reads "6080 IMP". I'm 90% certain on the 6080 part, but this key is very worn and I had to use a 10 power magnifier to read the number, so...
