I have a 339 marked 2/74 and I am pretty sure this is the original globe but I have seen some other 339s from the same period with different ones. Just wonder why the variation ?
I believe your globe is original and period correct. The most likely explanation for "different" globes is that they are replacements because the original broke.
Thank you that is what I thought might be the case. Does that mean the lantern was made in USA as well as the globe as I thought the body was Canadian?
