3 pair old Currans and two Carrs – this is really interesting and the first 1st hand reference I’ve seen to currans that early. Not sure what Carrs were.
If this is the earliest reference to currans, and they are described as "old", there may be a longer history of them than previously thought.

(I don't even know what a pair of currans is, but I did find it interesting that they are described as old, and this being the earliest reference that you've seen of them.)
