Never found one with my 1941 birth year. Yours is MK1 1941, one of the first made as that was the year Newhaven first started to stamp the "N" on the nibs. I hope you have the book Pen to Paper The Story of Newhaven Pen Factory by Malcolm Troak. Fascinating period of Valentine and Parker history. BTW, you may sometimes see a Victory with what appears to be a mismatched color cap and barrel. No mistake, due to material shortages during the war they used everything they could find since the demand was so great.
Great pens, thank you so much for showing this.
