Aust LP2 radio / ammunition covers

[Darrin Wright]

I am after any pictures (and hopefully dimensions) of a cover similar to the radio cover installed in some LP Australian BGC.
I have included a section out of the parts manual that shows the radio cover.
I have also attached a pic of a BGC that was on Ebay earlier this year, that was located in South Aust, but I believe this was bought by someone in QLD.

Has anyone seen this other cover of a more simpler construction?
Is this a late wartime production radio cover or perhaps an ammunition cover for a modified mortar carrier?
Anyone with another theory on these covers?

I think, and am hoping, that this simple construction cover is actually an ammunition cover, it looks right and the side mounting brackets would fit my brackets on my hull.
I will have to look at making 2 of these covers sometime in the future.

Thanks for any suggestions, pictures or dimensions.
