Belated, but a very merry welcome to the forum from the West of Scotland!
We have just the place you need for unpicking: the Stash & Grab, our virtual pub and home of (first and) last resort. Also, we have a thread devoted to culinary uses of frogs. Naughty critters!
welcome from Chicago. Have always wanted to visit Scotland but husband says too cold! Bummer!!!! Sorry to hear about your frogs, it can be frustrating but also a time of reflection (ha ha, yes bogus but thought I should give the "right and proper" answer!!!) I know that there have been several conversations regarding working with metallics but am not sure where to direct you. I suggest you start cruising the site, it is fascinating!
good luck, hope you get to post some pics, not hard at all. Sorry about your stash.
