The early first SDA 1's had a plug type interconnect socket. The middle area showing fuses are only placeholders for extra fuses. The fuses in service in-line are held in place under the black caps screws. The owner may have decided the use the receptacle as the original interconnect pins may have broken off. It could possibly work. Let me know if I'm wrong. -

May have been done by a tasteless University of Alabama football fan.
I once had a residential client with strange textured, dark red paint on her den walls. When I asked, she said it was called "Elephant Blood." She was a rabid Bama fan.

These are in my "neck o the woods". By the way @BlueBirdMusic. I have had no trouble at all with the belts you sent me! In fact, one of the T.T. I bought for now resides in Costa Rica with that goat you see in the picture above. Sent it as a gift to a great friend there and that is his goat! Thought about going to get those but I really do not need another set!!
