Sorry to chime in here, but those parts are all brackets from a TOW carrier. I´m currently restoring one, so I know those parts.
The top bracket holds the TOW day sight, the two smaller ones are brackets for the night sight battery, the long black part on the left is a bracket for the TOW tripod, and the flat plate with the holes is a bracket for the night sight coolant cases.
As for value, no idea. Those are just some of all the brackets for a TOW carrier, most of the large stuff (missile rack) is missing.
BTW: I am still looking for one of those cases for the night sight coolant. I managed to get one, but need a second one, if possible... (sorry for the shameless plug here)
