Thanks for the reply.

As I recall, back then there were problems with the MIST wallet and I went to the Parity wallet. Unknown to me, at the time, the parity wallet must have picked up the Mist one and somewhere along the line the MIST one got encrypted. I have no password for it in my notes.

Thought maybe I could find the earlier unencrypted one but so far no luck.

Therefore, there does not seem to be any road forward. I pick passwords at random so brute force is out.
