This may or may not be of any interest to anyone but I thought I'd pass it along anyway. If you have a mall/chain store called "Luxury Linens" near you, in their kitchenwares area they have a small display of items called "Mini-Gadgets", which are essentially miniature kitchen utensiles, and item #96508 is a nested pair of miniature nylon funnels the right size for various Ga1 uses. Price is $1.99/pair. Neither is more than about 1-1/4" diameter at the big end and have very small delivery ends.
