Raimey,

OK on the Czech proof marks. I thought they stopped using the N by 1962? My sources do not agree on that one. Also, didn't the Weipert facility close in 1945?

What a long history as documented by the proofs.... The 17.2 may be part of a Belgian mark indicating the choke. As for the weights, I was not aware the Czech proof house was marking barrel weights. Though I have never seen a Belgian barrel weight on a rib.
