This is a family mystery, and my mom and I would really appreciate any help. For my birthday, she gave me an old coffin smoother plane that she has had as a keepsake for many years. However, she doesn't know whether it was acquired by her father, grandfather, or perhaps great-grandfather.
If any plane wizards in this forum can help us pin down a range of dates for when this thing was likely made and sold, that would really help. Here is a photo gallery of every conceivable identifying feature I could find:

Thanks in advance!
