All About Pocket Knives

I've got this old Colonial 2 blade jack. It looks like the figure of woman under the celluoid scales, though it is a bit faded. I've found that stamps can be hit or miss with these. It sure has been around for a long time. Does anyone recognize this knife and know about how old it is? Insight will be appreciated.

To me it looks 1930s. I think the tip bolsters were common from Colonial in that era, and the curved stamp is an earlier one. Lates 20's to early 30's I believe.
