Just recently acquired a '67 337B and I have been exploring the message boards. Appears to be lots of good information posted here. Thanks to all who have contributed and support the site.
I have located a set of Service and Parts Manuals for the Airframe and the engines locally. Does anyone have any idea of what a good set of manuals are worth? They are definitely not in high demand. Are they hard to come by or readily available?
