Does anyone know an 'expert' (or organisation) who has any history on these WW1 Tank Spall masks? I have 2 which are both different. One is 100% original, the other I would say is too, but I cant 'prove it' like I can the first one... So if anyone knows an 'expert' or an organisation with any historic documents etc (makers details, plans, production details etc) I'd really appreciate details please.
Thanks
