The photo reminds me of an article in an early '50s issue of Wireless World - unfortunately long lost!!!

The article was a DIY transistor made from 2 point contact diodes ( OA81 IIRC ) carefully broken, one glued to a wood block and clamped in a laboratory stand. The 2 whiskers were then used to make emitter and collector.
