see my posts on walhalla:
Only two helmet makers existed in Hungary:
1. MÁVAG (Magyar Királyi Vas, Acél és Gépgyárak in Budapest
--maker mark "MÁVAG" ( DM in helmets produced for Finnland)
2. Magyar Waggon és Gépgyár in Győr
--maker mark "GY" ( DR in helmets for Finnland)
Negotiations had started between two more firms and the Ministry of War regarding the production of a new combat helmet type (M35) to replace the vintage WW1 models. The prototype was the german ET M35 helmet.
1. Weiss Manfréd acél- és fémművei Rt in Budapest (Csepel)
2. AJAX in Budapest
Only Ajax signed a contract for 59628 helmets but later this lot was delivered by the Magyar Waggon in Győr. None of them had ever started real helmet production.
