Vintage Mens Breast Pocket 13" 12K Gold Filled Pocket Watch Fob and Pen Knife

This is a very nice condition Bar Link Waldemar or Pony Pocket Watch Fob with pen knife. The Chain is marked 1/20 12K which is gold filled 5% gold. The pen knife isn't market but a scratch test seems to indicate 9K or 10K gold, but there's no way to know if it's gold filled or just gold plated. The pen Knife is Marked Colonial Providence Rhode Island U.S.A. That company is still in business today but first started manufacturing these small Pocket Watch Pen Knives back in 1926 when pocket watches were still widely used, and I assume that it came from that early era in the company's existence. Somebody had engraved it "Chicago" in the small cartouche on one side of the knife case. The other side also has a small carouche area for engraving that has not need engraved.
