CM5/3545

[Alan Baker]

Regular viewers of the forum will be pleased to know that I am nearly at the end of AK's material!

This card bears CM5/3545 and the franking, although not fully clear, appears to be FPO TW. Proud notes this as being in Eqypt and does not illustrate a double ring cancel. The picture on the card is clearly from France.

I have already noted from earlier material this censor with various cancels, including TX3 (Apr 1917 - 61 Div Train), T41 (May 1917 - 35 Div Train) and TW2 (1st June 1917 - 47 Div Train. All are in exchange period, phase 3. The last of these is dated three days before the one I illustrate. From memory, it is from the same sender

A couple of questions:
1. Is the cancel an adaption of TW2? Is it known to collectors iof Australian material?
2. Why is there such a variation of divisions?
2.
