Original catch tank ?

[Peter Barnes]

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

Suspect they might be another example of continuous development and bushfixes?

I guess they are for the crankcase breather system?

Maybe @JIMMYMAC knows something?

Breather tanks.

 

[Ole Nylende]

Are they filled with something or just a open box with two connections and a blinded port?

 

[JimmyMac]

Some are indeed empty.
My pair have coalescing filters inside. (my own idea)

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.

Regards

James, Well done, Can I ask which car ?

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

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.

Here's a photo of my car's engine in 1969. If you look carefully, you can see the catch tank in the foreground. It's an old metal canteen.
