Thank you all for the feedback.
I decided to leave the blob of solder. IMHO it’s part of the engines history and character. It just doesn’t bother me.
As to the sight glass bolts, wheteher original or not, they look cool, no one else seems to have them and they don’t leak. I worked really hard cleaning these up!
Many of you have much more refined restoration skills than me. For a first try at a frame off restoration of a Jensen, I am very proud of the outcome.
