Dear series'A' experts,

Now I asked the SOL list and the Mini list for help, but nobody knows for
sure how to solve the mystery with this head I bought last year. ONE DAY I
would love to either use this head on the 1275cc Midget, sell it again if
I can't use it or just use it as a decoration.
Oh, and BTW could you please (also) respond directly to me since I had to 
cancel the appointment to this list.
Thanks in advance!
Last May I bought this head for a series 'A' engine that said:

        (or 06M?)

I hope it's actually for a 1275cc engine, since that's what I have on my 

So, now I looked these specs up in David Vizard's book, it said:

12A185: Intake: 1.4",   Exhaust: 1.156", was mounted on 'S' engines 
(e.g. Cooper), color: yellow.

I took a measurement and found:

        Intake: 1.175", Exhaust: 1", color: blue

What's wrong with this picture? I couldn't find any clues in the book, 
but maybe he was only mentioning the biggest possible valve sizes? That 
would be in a different chapter (but he repeats himself quite often 

I would be glad to see if anybody else can come up with more reliable 
data for this head (12A185).
