mckay intake manifolds rare? or not

i have came across a sbc intake made by mckay, it takes either 8 single barrel 2 bolt carbs, or 4 of the weber ida style carbs. i was told they were popular with the can am type cars, neater than shit!! anyone have any info on them as i have never heard of them

 

Yes I have had a few of these. Mag or aluminum? The aluminum ones are not so hard to find like the mag ones but the mag is not really practical in a daily driver since the water ruins the mag if sitting. I sold the last one aI had a few years ago and now wish I had another for a project I am building. Let me know what you are going to do with it.

 

Any pics? That's my family name!
