 Hi  Lou, in the top picture, is that a test block set for micrometers ?  Frank

Hello, Frank. They are sold by MHC Industrial Supply, most likely imports. I couldn't find them on the company website, . If you can believe anything you see on ebay :-), they are being sold as Precision Spacer Blocks. Regards, Lou

Do they have holes in the center?

Hello. Actually, they all have female threads, so they can be ganged together for different size configurations. Set comes with 4 set screws, and an Allen Wrench. Photos show 2 of the 1" size ganged for 2". Regards, Lou
