Sid and Charlie are my pick. Carry on and do some more of the gang. A BBW matron would fit the bill nicely.
Ah! I was thinking it was Ronnie Corbett and (guessing) Tommy Cooper, but the latter didn't make sense without the fez. Great I am always intrigued by Pauls work as I have to work to get some of the references. They are gorgeous, by the way.
Now, the Major Pippin figs I still don't get. I was thinking Sgt Pepper, but the uniforms are not the same...
