Tater a month or so ago I took apart an oscilloscope that had a block of those Motorola transistors on them. They can go for a few bucks each. If you go to search box and type in oscilloscope my post is the second one on there with pics. Take alook at some of the boards I pulled they look a lot like yours. I got telecom grade for them $5.00#. The reason I got that was because the boards were plated with gold. You and auntie should try to peel back a corner of the green sheeting? and see if there is gold underneath. Sorry I don't know how to cut and paste on my iPad.
