Laws requiring county-of-origin labels seem to have been a response to German industrialization and protectionism.

The earliest I could find was by a John R. Norris in 1957 for a radio earpiece: There are a lot of behind-the-ear headphone/microphone combos, but that's not quite what you're asking about.

In the US rail road workers were often paid in such a way that their earnings usually got devoted to their food and board. In todays terms it would be like getting $500 a week but having to spend $495 at the company canteen (usually because there was no other option). Yes it did create some unrest, but not much. Another example (on the other end of the ...

As it happens, I'm getting partly paid in food today. There is a system to record how often I go to the staff canteen, and the next month that is deducted from my payslip. Of course that's only a small percentage of the total. And I'm not really forced to go to the canteen, if I don't go there nothing is deducted. But there are days where the schedule makes ...

After the political collapse of the Soviet Union came the crash of its industrial system. As a result, for some time during the 90s many workers were paid in kind. Here's a description: Starved for cash, factories reverted to paying workers and paying off debts to other factories in kind. Therefore, in many areas of Russia a barter economy emerged as ...

Yes, it is both appropriate and common to refer to things Americana before December 1941 as prewar. True, the war was raging since 1939 (or much earlier, 1937, if one considers what was going on in Asia) and while not directly involved in the hostilities, America was a participant indirectly via materiel aid to the UK, and volunteers flying in both China ...

Radios in the Soviet Union were the personal property of citizens and were designed for wireless reception, or for use on a wired network broadcasting. "FM-band" had (range УКВ OIRT (65,9-74 MHz)) in the Soviet radio. AM (amplitude modulation) was also labeled it as the СВ (средневолновый) диапазон - medium wave range.

Country of origin requirements were not common law until 1891. (MADRID AGREEMENT CONCERNING THE INTERNATIONAL REGISTRATION OF MARKS) In 1890, the U.S. Congress passed protectionist tariff legislation - the McKinley Tariff. This legislation, in addition to imposing heavy tariffs on imports and provoking a major depression in the United States, also ...

In Debt, the first 5000 years Graeber talks about how in England and Scotland for much of the 1800's, cash payments to manufacturing employees were irregular. To get them through months of non-payment, Graeber says people were expected to steal scrap and the the product of manufacture in order to get by. Meanwhile, tavern owners, grocers, and others have to ...

The rural population was indeed a significant source of demand for cars. From 1911 to 1920 the number of automobiles owned by farmers increased 21 times, while overall registrations increased 13 times. By 1920, more than a quarter of cars were owned by farmers. Rural doctors were also heavy buyers of cars, as they could serve a wider area, respond to calls ...

Looking at events called "ball" as described by the locals, roughly at the time: While Mr. Leese was erecting his mansion, which seems to have been rather a grand structure, being made of frame, sixty feet long and twenty-five feet broad, Captain Kichardson was kindly proceeding across the bay to Sonoma, where he invited all the principal folks of the ...

'prewar' becomes important when you consider the context in which wartime production functioned. In the case of a radio, it is almost certain that it's prewar, as consumer radio production essentially ceased during the war. During WW2, most of the higher end consumer goods were discontinued in favor of war production. A radio would have been the equivalent ...
