The bottom rat is made by Moore Drop Forge.
I'd have to dig out the collection to take a stab at the top one but I actually don't recall having anything similar to that design. Which brings me to.........is it / are they for sale?
EDIT: So, nearest I can tell, that style has been made by at least Lowell Wrench Co., Wright, S-K and Walden. Likelihood is that the ones with no markings are probably Wright.
