I told Olympic that the number on the old part was '015" and asked if '035' was an updated part number.
He put me on hold, and when he came back, said this was the case.
I will post side-by-side pics; the major difference I have noted is that there is a larger coverage of semiconductor material on the new part (only on the lower, or left side) than on the old.
The fly in the ointment came when I got to work today, and was invited to join my colleagues all weekend in an effort to finish out the fiscal quarter with a flourish.
After some horse-trading, I can probably minimize Sunday, which will allow time to remove the old pot, measure, and take pics.
Looks like I will not have time to completely put this to bed until next weekend, though.
