Keith,
Not my bike. I stole the pictures, didn’t buy it. I’d bet money it’s been painted a few times in the last 131 years. That is called a gallows seat post, gives you some adjustment front to back. The seat was more than likely leather, examples I have seen from that era are actually pretty comfortable. The right mouse gets in the shed and what you see is the result. That is a block chain on the bike, difficult to source today. I’d guess the front fork is bent, angles in the photo look odd.
Way older than where my bike interests are, but, interesting considering who made it.
Best,
Ted
