Here' the 1936 catalog page, the artist drawings are not 100% correct, the front mount on the scope is too far forward and the bottom picture of the H is not very close at all! This catalog has Marlin scopes, starting in 1937 they only offered Mossberg scopes's of a special design just for them.

I've seen this add before and the first thing that slaps me in the face every time I see it, is the way that man is holding his head to look through the scope of that 99. I could never get used to that.
