Oh, just noticed that second one is just selling the specimens that havent been done yet -- although there appears to be a pheasant she is selling 'done' . Looking at prices for these things, this could be an expensive thank you !!! You used to be able to pick them up for next to nothing many years ago in antique/curiosity shops and markets and local auctions.
You could think laterally of course and ask at a museum or private taxidermy place, if she could go along for a visit to watch a professional at work.
