Fantastic work so far - navy blue for the overalls. from memory the hard hats were white, no idea why but I clearly remember seeing the trains working and the other machines mill the peat as a nipper while helping turn hand cut turf near to where they worked in the midlands in the late 70s/early 80s - so I can assue you your modelling brings back memories ........ and of being eaten alive by midges (mosquitoes).
