Here is an old article from rgcc :

>1. no promoted pieces, without promotion moves: 109 white moves (W.Cross 1967)
>2. no promoted pieces                         : 144 white moves (J.Ban 1960)
>3. with promoted pieces                       : 218 white moves (Dickins 1968)
>4. with all 32 pieces                         :  99 white moves (HH.Cross 1946)
