For US aerospace contracts, one of the standard provisions is the disposal and destruction of any remaining products and tooling. This is done for compliance with ITAR regs, to prevent advanced technical information from reaching other countries. No buying a booster prototype at auction for you!

What was bizarre about (aboot) the Arrow program is that the entire company staff were fired, and the Canadian military was sent in to destroy all records, drawings, test data, and of course the destruction of the six flyable aircraft. The program was replaced with US made BOMARC missiles, so there's one clue.
