Sargent Plane ID

I have a Sargent plane I bought several years ago for the princely sum of $3 at a yard sale. I thought it was a 414 but it had a 409 Frog, (marked ‘409’).
Now I’m certain it’s a 414, and that the 409 Frog is what was put into about anything that used a 2” iron.
My question is, how do I tell if it’s a Type 1, Type 2, Type 3 or one of the newer less desirable? WWII era planes?

There are no markings of ANY sort on anything other than the Frog and the Shoe. The Frog has the aforementioned ‘409’ and the Shoe only has ‘Made in USA”.

This is one of 5 planes that I have, one is an old wooden Shipwrights plane dated around 1754 and the throat is about gone on it, so it’s not a user. It is cool though because at some point an owner engraved sailing ships into the sides.

I also have two Stanley No.9 1/2 and No.9 Block planes, one circa 1895 which IS a user, and the other from somewhere around 1990 that I got as a present from an old girlfriend. The newer plane was about as much use as the girlfriend, except I still have the plane! It lives in a box that I only bring out for friends and neighbors that ask to borrow a plane, but don’t have any idea of what they need. BTW, This is a BIG box… it contains all the junky/cheapo tools that I loan out and sometimes hope to never see again.

The last plane is a Stanley No. 5 1/2H that was NIB when I bought it about 30 years ago. It had some surface rust from sitting in someones barn or garage, but had never been out of the box that I could tell. It’s a really nice, well tuned plane and I’ve been known to use it to do more than it was designed for, I even flattened a 56” counter top with it.

Anyway, to digress make to the original subject, how do I tell which type of plane the Sargent is? I looked at as many of the websites as I could find that had anything to do with the Sargent planes, and even a few eBay listings. I’m not ready to go into a lot of books that I may only use once, so I hesitate to buy those, even though they may tell me more than I’ll ever want to know.

Any help will be greatly appreciated! Thanks!

Thanks!
