Great Pen, Michelle.
When I read your description, of matching a 1947 Mercedes Benz, I though you had added one of the Tri Star Balance Wheels from a wrist watch, that looks identical to the Mercedes Benz Star, into a cast Blank.
Ah, not so.
But I was Pleasantly Delighted to see the Glorious Blank you had used.
Your Fit, Finish and Kit Selection produced a Glorious Pen.
Congratulations,
Brian.
