from the looks and size, you're probably right.
Strange, tho, that it should fall off of its own. On the Skorpion, it is glued in with Locktite and together with the head described above, it is impossible to remove. The ones in the Skorpion are also hardened. I have alwas had to resort to milling the heads off once the triple-tree was removed and then turning the stubs out with a pliers.
re quarters
I am well aware of what the quarter looks like and might if I looked hard enuf, even find one. They are roughly as large as the old D-Mark coin for which I would have to look as well.
I personally have no problems with inches and feet and use them in my work myself as well as the metric system. We used the metric system in high school physics in Pontiac in 1962.
OTOH, 2 hundred years after its introduction in Napoleonic Europe, people in Germany (or as least in south Germany) at least still buy stuff by the pound or half pound. A metric pound, which was a condescension to the peons, is 500 grams or slightly more than the
US lb which is 454 grams. So I get a lb of meat from the butcher, a 10 lb bag of flour or 1/4lb of butter (called just quarter). It is very possible that at the market or on the butcher's front window today's offers are listed as €/lb and they use an antiquated symbol for this:
৳ I buy glue in a hundred weight bag from the manufacturer: hundred weight (
Zentner=100lb or 50 kgs.) Cement is sold in 50kg bags as well and one demands a hundred weight.
We buy whiskey etc in bottles called a fifth, 1/5 of a gallon, a traditional size for alcoholic content. Same here: all but the most inexpensive wines are sold in 0.7 ltr bottles. Originally 0,75 = 5x0,75 =3,75 and 3,79 ltrs = 1 US gallon = 1 Queen Anne wine gallon. The Imperial gallon is newer and was a feeble attempt to go 10 base or metric-like. A fifth is not 1/5 of an Imperial gallon. Two reasons for the change from 0,75 to 0,7 today: the buying public didn't notice the change so the actually higher price was accepted and offical, 0,7 is 10 base while 0,75 is the fraction 3/4 and everything is
supposed to be 10 base.
