This chair has been in our family for 5 generations now, in terms of items in the family, this one seems to be the most valued, now while I love this chair and can remember playing on it as a child, however after an extensive search, I have been unable to meet anyone who has given me any real info of value!I hope someone here is able to, because I have been trying for a long time now!
Older materials but made extremely well! Very heavy and sturdy, built well. I mean I used to jump up and down on it as a kid and it survived :)
The I-F-B at the top might be something, but again nobody has apparently ever seen one before.
