Broncco TX 6 question

[washout]

New to posting, sorry if I'm in the wrong section.
I have a 1970 Broncco TX6 and I was wondering did it come from the factory with a wood seat pan or has it been altered? It's in amazing shape otherwise but I just can't figure out the seat. Thanks for any help.

yes the base of the seat is wood and should have wingnuts holding it on (at least the 2 tx-6's I had were/are like that

Thank you. I just finished posting a couple of pictures of it and the bikes in the back room. I checked out your photos. We share a few bikes. Thanks for the help.
