In 1972 it was moved with us into Cabin Tranquillity. It is used several times daily. Today it is 37 years old and still completely functioning. My title here is Eureka because the oven lamp burned out a second time and I immediately went to GE to get another replacement. There were none available for that particular model and year. I wasn't surprised so I pursued further with internet searches with the part# and found one! It was $4.00 with no s/h and came in just a couple of days. I replaced it and am back in business.
I tell you this because I have always found it important to keep records of appliances and it has enabled me to know exactly what numbers and models, etc. would be needed for replacement parts.

There is so much waste today and being frugal, in my way of thinking, is being sensible and economical.
