Nice mirror, Hosman, and looks like you had a fruitful day. You're also quite canny in not going for that chair and walking away. It makes you feel quite pleased with yourself if you can be that objective, and is kinder to your purse.
I walked away from two pieces on Sunday, the two vases my wife had liked, only because of the condition. Then quite a nice clock, originally priced at £85 and they came down to £60. I told them that in my opinion it was worth (to me) £45 - £50 because of the work needed, but they weren't prepared to come down any more. It worked well, sounded sweet, and the case was in pretty good condition as it was an 1890s piece, but the dial was in a terrible state and it would still require a complete dismantle and clean. It'll probably be there next week, and the week after, so it's not yet lost if I change my mind.
