Thanks for the info, posted a few more photos in a reply. Looks to me like the mast is slightly pinched in where the spreaders attach.While hope springs eternal, bent masts do not spring back. A mast that has a curvature due to lack of support will have a very gentle large radius curve. The photos posted by the OP do not show a large radius curve. The bend is a short radius curve at the point where the compression loads are very high. This compromises the integrity of the mast column.
Closer photos of the mast section near the spreaders would be helpful to better understand the mast's integrity and the nature of the bend. However, I think the optimism expressed here is misplaced. I've seen bendy unsupported masts, I have one, this bend is unlike the naturally occurring large radius bend seen on bendy masts.
