Sold 1933 Ladies Elgin / Swallow ??

If this is a structural issue, I have a repair idea that I believe to be strong, permanent, and invisible. (Note: I am not an engineer and I have no idea if this is actually a structural issue.)

The seat post is a strong steel rod that goes through the entire section in question. If it were epoxied in place, probably lower rather than higher (with proper surface prep, of course), I would think that it would keep the two parts together, keep them from moving, and keep them aligned properly.

Yes, it would mean that the seat post could no longer be adjusted, but to me this seems a worthwhile compromise for a repair that would keep the bicycle functional and allow it to retain completely original appearance.

Thoughts?

a frame builder can repair that, there are tools (heatsink / purge fitting) that can be put inside the frame tube and allow the tube to be brazed without permanently seating the post.
