Vtg Antique Cast Iron Caloric Floor Heating Vent Grate Department Store Auburn

Description

Large and heavy vintage or antique cast iron Caloric vent/grate. Just acquired from a private estate and was told it had been removed from a department store in Auburn, Indiana many years ago before the store was demolished. I didn't think to ask what store it came out of. This would look great in the same room with the decorative cast iron heat/cook stove with the cottage scene that I am offering in another auction...the stove is local pick-up only.
My guess is antique but is not dated. Has a marking of CAL . 480 and 133 on the bottom. No cracks or repairs seen. Very heavy and will be expensive to ship. Will be wrapped in multiple layers of corrugated for protection and box will be marked Fragile. I will probably be looking to purchase a couple large thick pieces of foam to package this in before wrapping in corrugated.
Grate measures about 33 3/4" x 33 3/4"...inside circular portion that is removable measures about 23" diameter. Weighs 56 pounds 15 ounces prior to being packaged. Package will be large and weight will probably be 70 pounds or more by the time it is packaged.
There is some minimal light rust and looks great for age. I think a good portion of the brown you see may be the original paint. The light rust looks like it is only in a few small areas.
Local pick-up would be appreciated. If wanting to make a local pick-up I will lower the price to 0 for not having to take the time or purchase materials to package...or 0 if you purchase the cast iron stove I have listed for 0...is a very neat looking stove.
I am in far northwestern Ohio and about 10 minutes from Indiana and Michigan. I am about 5 minutes off the local 80/90 Ohio Turnpike exit and very easy to find.
I am using 3 business days for shipping and probably don't have to explain why...will give me time to acquire all needed for packing.
