There is also a printed Qty that appears to read 2 fl oz with a hand written 8 over the 2.
There is also a sticker with 25c
The bottle is in overall good condition as pictured, the label is in good condition the 25c label has a light peel to the edges. the cap is made from metal and has some minor scuffs and minor discoloration.  
The Bottle I believe is from approximately the 1950s. The contents do separate though it also says to shake well so I assume at least some separation is normal. Due to its age I can't verify whether the contents are still good. 
Still the bottle and label are interesting.
