I tip my hat to Les Munro but think it a disgrace that this memorial is not kept at public expense. While I would be willing to put hand in pocket for some kind of fund I don't think it should be necessary nor should Sqn Ldr Munro have to sell his medals.
You would have thought that the Fail would have got the abbreviation Sqn Ldr correct. Or on second thoughts hardly surprising that they didn't.
