Hmm.. I spent some time looking for these. It says "Made in England". I posted a few cropped images below but the marks are still unreadable to me. Maybe a loupe would help? Anyway - I too came up empty handed - But they are neat!
Purely speculative but, I have an old pencil sharpener from my g-pa who was an artist. It has the same style of leather case. It still has it's price tag ($.95) which makes me think it's from the 1950/60's... Speculation on speculation but thought I'd throw that in.
Also am posting this here mostly b/c I always forget the dates on "Made in ________" - Definitely 20th century. This is from a pottery site but am sure the same applies for most items.
http://www.thepotteries.org/mark/general.htm'England':- Inclusion of the word 'England' in marks denotes a date after 1891, although some manufacturers (Thomas Elsmore & Sons for example) added the word slightly before this date. 'Made in England' denotes a 20th-century date.
It was William McKinley (the 25th president of the USA) who introduced the highly protectionist McKinley Tariff Act of 1890 - this imposed tariffs on many imports (including pottery) in order to make it easier for the American manufacturers to sell their products. It was a requirement of this Act that all such imports carried the name of the country of manufacture.
This provided well-known marks such as "Bavaria," "England," "Nippon," - indicating the country of manufacture.
In 1921 the Act was amended to require the phrase "Made in" preceding the country of origin, The labeling at individual British potteries varies somewhat from the 1891/1921 dating requirements described above (e.g., Wedgwood adopted the "Made in England" around 1908/10 and may have used it on some pieces as early as 1898),
