I live in Waterloo and I ust cleaned out a shed on a piece of rental property. I found a large wooden incubator cabinet style. 4" high X 3" wide x 2" deep. Has 2 dials temp and humidity on the top. Not sure if it works, but you are wecome to it.
PM me, I can text or e-mail you some pictures of it tommorow.
If you dont mind the drive to Murphy Nc, I have a almost new solid pine, 288 egg capacity cabinet incubator. Automatic turner with hatching tray. $400. Hatched in one time with 90%+ hatching rate. Ready to go, just add eggs. This is the actual incubator shown in this link https://www.backyardchickens.com/web/viewblog.php?id=41326
