I thought I saw the old man with the wine bottles sold by Tamiya in a little plastic bag but I am unable to find it or even confirm it. Can someone let me know if they know?

I don't recall seeing it seperately, I have only seen the figure set available with the Churchill.

Alan, it was, kit #89618; British tank crew (4 figures). 3 tankers and the old man with the cart.

You can try Tamiya USA. You can order the sprues you need from them. You will need the kit # and sprue letters. I think they are sprue f and g. Hope this helps.

Yes, the crew and Civilian with cart were released (at least in Australia) as a bagged set about a year after the kit was released (95 ish?)I have a few of them in the stash as they also contained the clear sprue from the kit with goggles, hurricane lamps and bottles. A very useful set indeed. THey also released a few other crew sets including the Tiger crew.
