Appliance age determination website

[fyrmnk]

Anyone used this site? It's geared towards ohter appliances in a home but I came across it last night while trying to determine the age of an old Montgomery Ward air conditioner. It had it and determined it was over 40 years old (yeah, it was in baaaad shape).

Haven't tried it on any other appliances yet but worked great for that one.

Scroll down and it has the place to enter the information.

**Just realized I probable should have posted it in the Appliances forum instead of HVAC, but did work for this AC unit.
