since i just can't come up with the cash that the "Old Rifle Scopes" book demands these days i'm asking for Old Gunsights And Rifle Scopes book for fathers day. my question is this, is there some info in the first book that does not get covered as well in this new one that seems to be a combination of his first two books? or do i still keep a look out for the first book as well to add one day? i'm not looking for collecting purposes just personal info needed.
