5 Vintage Handmade Tube Testing Socket Adapters test tester Johnson Ceramic plus - $30 - (Mountain View, AR)

Five vintage handmade tube socket adapters. Three of the ceramic sockets are marked Johnson. I believe these were used for testing the larger tubes that fit into these ceramic sockets on tube testers not normally equipped to test them. The working condition is not known. Selling "as is". They show wear and need some cleaning. One of them has a large amount of glue on it. Please view all 12 pictures.
