Regarding the seatpost, it looks like someone has either tried to squeeze the wrong sized post in the seat tube or tried to free up a stuck seatpost. Either way, they've made a mess of the seat tube. Someone else on the forum reckoned it could be bent back okay, but that removing the seat collar is more of an issue.
You're welcome to view it if you wish. We're heading down to the beach in an hour of so to make the most of this freakish November weather. I'll pm you my number and if you want to give me a call, we can sort something out.
Cheers.
