My latest acquisition. I think its an Adrian M26, although it seems smaller than my other - did they come in different sizes? Unfortunately the comb is missing. Despite this its got a nice patina throughout, paint looks original and the liner is complete (although boot lace is suspect). The strap looks original to the helmet but it looks to be incomplete. inside, there's a name scratched into the rear - looks to be Lagaiz M?
Really like it as is but if someone has a comb for this helmet, please PM me. And thoughts welcome as to what it actually is!
