I received Jack's first three drawings in the mail this weekend and thought I would add something here. First I would like to say thanks to Rich for his posting, and add that I am only providing information and receive no gain financial or otherwise from the sale of these drawings. The following statements are my opinions, and as such they are just opinions and I don't consider them any more right or wrong than anyone else's opinions.
To me, a drawing is a tool, and like any other tool, only the individual can decide what they are willing or able to pay for that particular tool. I want to make it clear that I am not disrespecting any available drawings out there, whether you create them, market them or just own them. Some of the plans commonly available are generic to a school of building or based off of contemporary work. There is nothing wrong with either, and they can be of great value depending on your needs.
Are Jack's drawings inexpensive? Probably not to the average person reading this. Are they a good value? If you are wanting to build specific gun or rifle, one that is architecturally and dimensionally correct based on an original antique, that is often unpublished and/or unavailable for study elsewhere, they are a bargain.
Thanks for looking,
Curtis
