Original catch tank ?

I was given these by a good friend and respected GT40 man but unsure of their origin. I have asked others but no conclusion. I have searched photos but not see them.

Some GT40s had tanks at the top corners near or inside the body mounting bracket.

Anybody know ?

Thanks, Peter

Ole, The items I have are empty.

James, thanks for the photo, I have seen similar, Sean spoke of them, no one seems to recognize mine.

How have I not noticed these in any of the photos i have looked at.

you watch, when I get to the point of drawing up the rear bulkhead/firewall/roof, ill start noticing these little bits.

It does remind me a little of P1015s dry sump oil tank, that was in this area.
