Not everyone objects to looking up information in "the book". If you are new here or own just one Parker and want to know what it says about your gun, ask.

If I see the post I'll answer. No need to buy a book for a single gun lookup.
If you run across a gun somewhere and need information, then too, it's OK by me and I'll answer up.
If you keep asking though,

then it's time to buy a book and I agree with Brian; you need one. At times it does seem that there are more "lookup" requests than one would expect.
