The way I see it you have pretty much 3 standards of amour available.Indian/ backyard armourer
MJ (best armour)
The Masters (Jeff, McPherson, etc. etc.)
I'm currently losing the weight I've put on since I moved here (60lbs in all). I'm commuting to work on bike and have changed my diet. So for the time being I do not want to waste money on a half harness that might not even fit by the time I get it.
So, I want a one piece Sallet with the cut occular and lined to start my kit.
example: http://www.glasgowmuseums.com/assets/slideShows/E.1939.65.ai.jpg I really like this style
The following is my problem.
The Indian Helms are not even an option
The one from MJ (SS 4.4) is wrong (occular too large and tail too short).
The Masters, I cannot afford $900 or more for an unlined helm.
So is there a source between MJ and the Masters?
To where I can get a historically accurate Sallet better than munitions grade, lined for about $5-600
I know you get what you pay for in this, so I'm not trying to cheapen the Art, just curious.
