thanks a lot for all your comments,
but these two helmets are in my family since 1921,today,i have asked at every old people in my family if they were repainted but nobody can be able to give answer,just that they stay some years in the attic and after they come back in family living room and now in my office
may be,they are a tourist souvenir from the flanders field????
and the 64 in white isn't an size marking....and isnt a satin varnish... just many,many layer of wax!!!
Regardless of what you've been told, they definitely look to have been modified in no fewer than one way. The helmets may have been in your family for that long of a time, but they have been altered. As for Flanders Field, maybe and maybe not, but it doesn't change how they look now. Sorry about your luck, friend!
