Odd that your sale comes up now, as I in am in the process of repairing one exactly like yours I bought off eBay. Mine arrived rusted with broken "plastics" and damaged steel plates, but after a week of repairs it turns out to be a very well designed (although requiring some transition of rivets to steel nuts & bolts). Initially I felt it was a piece of eBay junk, but I am now very pleased with the room and ease of access to the internals of the case.
Who ever buys it will really enjoy the design and roominess it provides the user. Good luck on the sale and God Bless.
