I've seen prior posts on Shotgunworld re: Iver Johnson shotguns, but have not seen chart that would translate serial number to date of manufacture. I've inherited my Grandfathers shotgun- I am guessing circa ~1920s but looking for facts.

Iver Johnson Shotgun Serial Number Lookup

Hello everyone. Is there a resident Iver Johnson expert here? I just picked up a complete barn find bike last weekend and wanted to try to get an idea of when it was made. The serial number is 256466 and so far the only thing I've notice in the material I've been pouring over is the little indentation where the seatpost cinch bolt goes through the frame. I may be wrong, but I think that tells me that it has to be 1909 or afterward. The fork is not original and appears to be a Schwinn fork. I completely disassembled the bike to find that the steerer was lengthened at some point to fit the tall head tube frame. I'm totally green to wood wheeled bicycles, but I'm really interested in learning more about the history as well as what makes a bike correctly restored. If you're an Iver Johnson collector or have even one, I'd love to get some photos from you. I tend to over research things. I've posted a picture of the complete bike and would love to hear someone pick it apart. The previous owner was skeptical about some of the parts being original. Thanks in advance for any and all help you can offer!
