Cool! That's the big Brower round galvanized goose egg incubator, aka Brower 846. Works for chicken eggs too, it holds a bunch. Even though I have Sportsman cabinets I use my Brower when the geese start laying. It works great. You will want to get a new wafer for yours. You might find one at a local feed store. If not most hatcheries or places that sell poultry supplies have them. If you have to order it I'd suggest getting at least 2 so you will have a spare. I have the instructions on a file in my computer. PM me your email and I'll be happy to send you a copy along with some helpful hints.
