One of the 1st vintage razors I purchased -- back in my early days of collecting and searching for the best shaving razor -- was an Aristocrat Junior. I purchased it from a TSD member who no longer seems active here -- but had a very nice uncased Junior. I have since found quite a few of this esteemed razor -- cased and not -- with the solid head plate and not. But I never had one in as pristine a condition as this one -- complete with the shipper and price listed. This could be polished a little more, but with the cardboard head "blade" and the original blade case and full instructions -- this set is straight from the time machine. And if you haven't yet experienced a shave with a British made 1949 (or 1950) Gillette Aristocrat Junior -- I heartily recommend it and hope you can find one to try out. You're bound to love it. 12 pounds sterling (printed on the side flap also) -- seems pretty pricey for its day. With the solid -- hefty and well-balanced -- base plate. Great nickel plating. Simple head protector and razor instructions. The 1949 model No. 52 -- what a great razor and wonderful shaver.
I know this thread is old. The OP mentions the price written on the box as 12 pounds. I think its more likely to have been 12 shillings. I was born pre-decimal in the UK and thats how pounds/shilling/pence were usually written. So, 12/- 12 shillings/no pence. If it were pounds it would have been 12/-/6 (for example 12 pounds, no shillings and sixpence) Here is some info confirming the liklihood of this being the correct format for that pricing. https://www.1900s.org.uk/1900s-coins-writing.htm
The shilling was a coin worth one twentieth of a pound sterling, or twelve pence. So 12 pence x 12 (the price printed) would make this set price £1.44 - one pound, fourty-four pence ?
Oh, I have to do (and remember) my pre 1971 math. 20 shillings to the pound, but, 1 shilling ended up being 5p in new money, So 12 shillings would have converted to 60p EDIT to add: Found this after posting https://www.retrowow.co.uk/retro_britain/old_money/old_money_converter2.html and this https://www.in2013dollars.com/uk/inflation/1940?amount=0.60
