They have had their bases removed to better match the size of the plastic figures.
First command platoon, the NCO has an old Thompson with the forward pistol-grip.
Likewise with the second NCO figure. At first, I tried to make the Thompsons drum-fed, but this proved beyond my abilities - for now. This figure was formerly a first edition Airfix commando officer; not hard to make that one look better!
Borrowing from Paul Foster's idea all figures had gas bags added to their fronts, plus back packs and bed-rolls added to their rear.
The Airfix figures were a bit taller than the Matchbox ones so I removed their bases for a better match. The proportions of the two are happily very similar. There is still much to be done with the paint work, etc, but once I complete these two companies plus the LMG platoon I'll see if I have enough figures left to make a full battalion.
