Adrian,
Thank you for the positive comments. I hope you are enjoying reading it. There should have been no surprise that you were acknowledged ... you were very generous in answering my questions on the 17-pdr in the Firefly which helped in my understanding of the connection between the earlier 17-pdr mounting in the Aust Cruiser tank and the later British development that resulted in the Firefly. Always try and give credit where credit is due.
Mike
