Madwolf,

I have a book.. "Standard Guide to Razors" Identification and Values... I like this book.. only 12.00 approx ... at several places online... amazon..ebay.. and at stores....borders and barnes and noble.. Lots of fun information and lots of pics and examples of great razors too!

Anyway.. on page 73 of the book they have a page called Razor Dating at a Glance.. according to the book.. Framebacks started into production about 1810 and were made through 1870 or so.. That said... I'm always looking for a nice frameback... It would be the oldest razor I own..

Another example are wedge ground blades... started in 1740 and stopped in 1870 as well... If the book is accurate .. that is nice information..

Hope that helped.

Let us know how it shaves too.. you'll be shaving with a blade 140 to 200 years old!!! Wow!!

Have fun!
