vintage built by GE. I don't think Roper ever used a slide up self clean window guard. If the cloks work, or can be cleaned and or repaired, thats a great range.
If the lock motor isn't working, an easy repair too.
This was built by Chambers they were neat looking but often had problems with the oven if used a lot, I will not say anything bad about the DW except to say at least you are getting a great trash compactor out of the deal.
