Can anyone help me identify these parts?

[Confettihead]

It seems that the portion of the adapter that slides into the Edison bayonet fitting has swollen to a point where it will not insert at all. I guess both parts are somewhat useless to me.

You can get a file and some wet sandpaper and try reducing the swelling- this thing isn't so valuable that some work will devalue it.

I had the same swelling problem with a pot-metal Fletcher adapter. I removed the bayonet pin from the fletcher, then wrapped some medium sandpaper around the swollen end and gave it enough twists to sand it down. Forty years later, I am still using that adapter.

I will definately try this. Thanks!
