Gas detection brassard with unusual marking
Paul Smith sent me photos of a gas detection brassard he has had for almost 20 years and that has an unusual marking: 8/42 1 SL. It seems the usual “& R” is missing at the end of the code.
It looks genuine though, so I have added it to the list in the article.
Meanwhile I still have no idea what these letters stand for. All insights are welcome.

Hi Wouter,
8/42 most definitely implies the date of manufacturing, i.e. August 1942 in this case. In my opinion the 1 is a batch number and the SL is the maker’s marking (abbreviation of the company’s name in which the L could stand for ‘limited’).
Hope this helps.
Best regards
Ken
Wonder if 1 identifies the product as ‘the brassard’, the SL, possibly being the newer logo for S Ltd, & the following letters (or lack of in my case !) identify when the batch was made during the particular month, to identify out of date or faulty ? Just a thought.
Regards
Paul
