Below is a scan of a YMCA cover sent by a serviceman in April 1941 with a QE1d green single franking tied TARRALEAH / TAS. datestamp paying the Defence Forces concessional letter rate and with a blue boxed SOLDIER'S LETTER / BRIGHTON CAMP cachet alongside to identify it as entitled to pay this concessional rate. This item was sent from Tarraleah, some 100kms north of Brighton, presumably while the serviceman was on leave, the cachet having been applied to the cover before he received it. Most such items have a standard "Department of the Army / Concession Postal Rate" cachet which was used throughout Australia, such as the one on the cover in the second scan which was sent from Brighton Military Camp in October 1941 with a QE 1d green tied MIL.P.O. BRIGHTON datestamp.
So here are my questions:
1. why did Brighton Military Camp make up its own Concession handstamp?
2. is this cachet seen frequently? [a quick Google search did not locate anything similar shown on the web]
3. did this cachet continue in use concurrently with the standard "Department of the Army / Concession Postal Rate" cachet?
4. was the first cover entitled to be sent at the concessional rate given the serviceman was presumably "on leave" and not "on active service" at the time?
looking forward to your comments
