Aussie MkII Camo

[aussie mick]

G'Day fellas,
I just picked up a 1941 Australian Camo MkII.
Ive got a couple of questions im hoping someone on this Forum might be able to answer for me.Im wondering if it might be a refurbished WW1 Brodie.
There are some markings on the helmet that i have not seen before,
Stamped on the underside of the rim is the Number 4 and a Broadarrow,and the liner is stamped--7 1/4 LP Ltd.
Also can anyone identify the Camo Pattern.
Thanks for any help
Mick

Interesting that the camo is in the style of Australian army in the jungle but the wrong colours, hope you can find the answers.
