Some confusion surrounds the type number prefix of P.R. tubes. some tubes located have a paper label stating GPR-- , for example GPR3 and GPR4. Wireless World October 9, 1929 does show this. The tube review of wireless World November 27, 1929 shows the tubes being prefixed PR--,

PR2 (PR2) Foreign ?

On this tube (valve) we find the writing "FOREIGN" with no further indication of the manufacturer.
My assumption, it was mainly used and/or sold in the UK.

Question: What is the meaning of "FOREIGN"?
May be a warning: Not British Made, manufactured outside the UK!

Who can explain it to me?
Many thanks in advance.

Hello Wolfgang,

Thank you for drawing my attention to this question.

I am not sure of the rules that were established for this, but certainly it was a Government directive that many items manufactured outside the UK must carry the "foreign" marking.

This seems to have started in the 1920s and examples persist late into the 20th Century.

As regards tubes, one can even see this on Mullard tubes that were manufactured in Philips' factories and rebadged Mullard.

Presumably the directive was to enable buyers to choose, and "buy British" as was encouraged by Government,  but also was of importance as regards import duty assessment.

Perhaps others know more precise dates and directives.

Best regards,

Roy

Hallo Wolfgang, here are some additions. (shortened)

In the second half of the 19th Century the industriel revolution swaped  from  England to the continent. By and by goods from continental Europe mainly from Germany were brought to UK. 

Most of them were imitations of british products but almost of very cheap made and of poor quality. As a warning the slogan MADE IN GERMANY was created.  On 08.23.1887 the "Merchandise Marks Act 1878" was placed. After that, all goods had to be marked with "FOREIGN" or "FOREIGN MADE" 
In 1891, the labeling regulations were tightened in the Madrid Agreement of 1891.

Further on a kind of suport and protection of domestic industries took place by campagnes like BUY BRITISH and I´M BACKING UP BRITAIN

 

The picture is showing my Blaupunkt VII (Ideal) from 1928
