M*A*S*H Eyeglasses Info?

[TheTrekNerd]

During the entire run of the show, any character who wore glasses, wore the same type of glasses, whether it was Radar, Potter, Mulcahy, etc. With such a widely-used prop, I can find no information on them anywhere at all. What brand / style were they? Since they were used for 11 years, there must have been a great many of them used in the show.

Anyone know anything at all? Thanks!

I think they are US Army "P3" eyeglasses.
