[Stoves] Skirt on institutional stoves

[Cookswell Jikos]

Merry Christmas to you too Paul!

Perhaps drop a note to Mr. Taps from Wonder Stoves in Sierra Leone - he has
invented this (among many others) excellent institutional stove seen here
https://www.facebook.com/wonderstoves.sl/videos/889607707869718/ that
vastly improves conditions in this very hectic and hot looking kitchen.

All the best,

Teddy
