Manfrotto 074B and What tripod head is this ?

[gliderbee]

I have bought a used Manfrotto 074B tripod. I keep reading the legs can be spread at uneven angles, but I don't see how that would be done. Can anybody explain this (or point me where it is shown) ? Can the centercolumn be inverted for low-level pictures ?

Also, there was a head included (see pictures) with a quick coupling attachment (I think the last is Manfrotto also). The coupling plate has six sides; I don't seem able to find these. Any idea where I can buy extra plates ?

Thanks,
Stefan.

The Manfrotto site no longer lists the plate(030) separately but it is available with the same adapter you have. Used is the way to go.
The head is a Gitzo Rationalle 5 I think.

Thanks !

Anybody an idea on my questions about the tripod itself ?
