G'day, Ken.
A big welcome, mate, from someone else who does figures as well. I had two uncles and a great uncle who were in New Guinea, luckily they all came home. Was your grandfather with the 41st DIV, as Uncle Alex mentioned working with them in NG (he was with a 6DIV transport company and they were using some of the 41st's trucks) in some of hi letters.
I'm sure you'll enjoy this board, it's one of the friendliest I've ever seen.
Cheers.
Dal.
