Here's 3 more buttons I found in England. The left and center button I believe are one piece pewter. The left one has a 3 in the center, nothing else on the front or back. The center button has a crown over what looks like a flower (maybe a rose?), and there again, nothing else front or back that I can make out. The right hand button is a two piece brass domed button with a crown over a shield and two animals (lions?) standing on each side of the shield. The backmark is mostly readable and what I see is C ? (& maybe?) J W?LDUN. LONDON. Age and use would be great to know. Thanks.
