3 Branch Manifold for B series engine

[zapper]

Hi All I am a new member to this forum.
I have a 3 branch manifold that I bought for my MGA many years ago. By chance a Riley 1.5 owner was looking for a manifold. This led to me taking some photos and forwarding to him. Unfortunately the manifold is too big to fit his car. I am therefore wondering if it is for a Morris Marina 1800. Centre port 35mm square, outer ports 35x30mm, Bore at outlet approx.40mm
I would be interested in hearing any-ones comments
Regards Brian

It could be a Marina or MGB - iirc the MGB one is "taller" and the outlet sits too low for a Marina. There may be more photos and dimensions under the "Technical" section of the forum.
