Meriden was a prolific maker of shotguns and small inexpensive revolvers. Most were sold to hardware stores and mail order companies. Meriden would put on any name the customer wanted if he bought a quantity, so Meriden's own name is not very common on guns it made. The revolvers usually sold for around $2. There is a mild collector interest, but only if the gun is in near-new condition, which most are not.
For the young folks, a punchboard gun (or anything else) was won on a punchboard, something commonly found in almost every small store up until the 1950's. This was a thick cardboard gambling device with many holes covered by paper with the hole positions printed on it. Using a metal punch, the bettor punched through the paper into the hole and pushed a tiny slip of paper out the back. The paper had a winning amount, a prize to be given by the store, or a "sorry" note. The cost was usually 5 cents a punch or 3 for a dime.
Most states outlawed punchboards when they went to state lotteries; the state does not appreciate competition.
