Green and silver stripes is an occasional thing, and depends entirely on the area.
Its milk that has been blessed by a Rabbi, therefore making it acceptable for people of jewish faith to drink it during their holy period, the name of which I can no longer remember.
Express dairies in London had to pay a rabbi to stand next to the bottling line saying continuous prayers in order for the striped top to be fitted. The customers had to order it three days in advance and I think it cost a penny a pint extra, at a time when the normal pint cost 7NP
There, that would have won me a million on the telly, wouldnt it?

I dont recall seeing the metal named. Is it stainless, EPNS, or chromed iron?
As the dishwasher was mentioned I think we can assume its stainless?
i would spend time digging out the remaining powder and the rest of the tang (very time consuming though) then get a new tang welded on and replace with epoxy.
If its special to her, treat it like Triggers broom.
