Here's a couple pictures of the blue HJ tags. The one on the 507 is normally seen on SA and political stuff. First photo is a strap with the "TA" designation for textile manufacturing prior to 1936, and the second is the later "A4" in blue prior to 1938.
maybe someone has been naughty in the past or if made late any tag will do sort of thing who knows good to hear 201 is on is close to where it should be in a great collection and as for your other comment yes you got me thinking you bugger
