From Fairchild collection. Object consists of 3 transistors in open lead frames and one transistor with cap attached. Significance of this group of devices is not known. Foam in display box is badly disintegrated and the leads of the uncapped transistors are strongly adhered to it. Suspect that it may also be causing the corrosion noted.
