I am very pleased with these results!
After a soak in Evaporust it became evident that there were pin holes throughout the nickel plating. There was a fair bit of rust hiding under the nickel!
Since this plane is going to be USED, not collected, I decided to go for it and remove all the nickel in order to get the rust in its entirety.
A very light sanding on the tote and front knob followed by several coats of thinned shellac.
