I think we still need to see the flats of a lunette Ideal that has smokeless proof stamps applied, by a proofhouse, before we know one way or the other. I sure haven't seen enough to draw any conclusion.

The Manufrance catalog was like the Sears catalog of the same era. I'm sure they would send you, by post, anything in it, just like Sears would.

Those were the days.

Best,
