What is wrong with leaving it in place? If the purpose of the foam is

I personally would no bother as I suspect that a decent load of
polysulphide mastic or some 797 would do the job without it
I suspect the purpose of the lead is as a dpm (which is required for
present building regs) and is only commonsense. I have been putting
in windows with dpms to isolate timber masonry contact for over 30
years and it is bog standard dry rot prevention practice.

Interesting. I've never seen this. And the pic looks like it's a pretty
old house.

having been up the ladder and looked and thunk again
i've now squirted some flexible sealent between the lead and the wood,
and will fill the big gap between the lead and the stone with foam
and some kind of filler,
unless better ideas come along.

thanks
