Hey fellas I have at least 4, maybe more Military Issue Cambros. These were introduced in 1999 to replace the old school mermites. The will hold a full steam pan, up to 6" deep. They come with three 1/3pan 6" deep containers with rubber seals. Here is a description of the units from a website:
The IFC is used to maintain food at acceptable serving temperatures at environmental extremes (-25° F to 120° F) during transport from field kitchens to soldiers at remote sites. The IFC is durable, uses standard size steam table pans, allows for easy field sanitation, and is produced using high density polyethylene for impact resistance. The item dimensions are 25" long by 17" wide by 9 1/4” deep. The container is issued with three 1/3-size, 6"-deep stainless steel insert pans with covers and gaskets.
I can email pics to whoever is interested, all are in great shape. Extremly similar to the civilain model UPCS 160. These retail for over $100 without the stainless steel 1/3 pans and lids.
Price is $75 for one cambro and 3 pans/lids plus shipping to your address. I'm guessing unless you live in Alaska shipping should run around $25.
