Sorry for the delay, I never seem to get time to myself any more. Pics attached. Not sure what the white stuff is or why it was put there as I got the post with a frame and this was already done. Looks like paint, perhaps some form of undercoat for an attempt at a restore that didn't ever get finished? I toyed with the idea of paint stripper, but as I've not had the need for using it I have never done it.
If you want it, and you've said you can collect, it is yours for the princely sum of Karma.
