(That other feller with the Coronado open oscillator coil might find this useful.)
It's broken off too close to the winding. I got a BFO coil from a scrap receiver.
Regarding the aspirin trick, a Cuban old radio restorer uses aspirin for solder flux. Read about it on the UK radio website.
I guess, we don't know how good we have it here!
One of the UK website members sent him some rosin core solder.
