Japanese Occupation Oceania P.1B Half Shilling Block OA PMG EF 45

A Half Shilling note from Oceania under the Japanese Occupation period with the Block Letters of OA as catalogued by Kraus as P.1B & also catalogued by Schwan Boling as SB2212A but unfortunately, this is a low grade note. 
Wishing for a long time to upgrade to a PMG 66 one as grapevine has it that someone Down Under has it. So, if you have it, raise your hand & say what price that you want! Everyone has a price, as such, don't say it's NFS!
Also looking for the Block Letter of OB got this Half Shilling issue and wouldn't mind starting from a lower grade one as a start.
