The type studies found online or in books are an interesting look into the history of Stanley hand planes.
Often, they become rigid in their interpretation or use. Hand planes were not put out like a new year model of an automobile. Once a type study is put together, it gets distributed and becomes difficult to make changes.
For my own enjoyment, I modify an old type study. But even that becomes inaccurate as some information is not entered or I may have multiple copies and forget which is the main copy. It is mostly just for fun.
Here are variations in the type 9's evolution into the type 10.
From all I can tell, they date from early type 9 to type 10 viewing from left to right. I suspect there are type 9s that look like the type 10 on the right, it is just that I do not have one, yet. The planes are a #4, #6, #5 and a #4. I almost threw my #5-1/2 in the picture, but it had a rib somewhat like the #6. Now I am going to have to go make sure it has the neck around the lateral lever.
140017
Notice the notch at the bottom of the frog and how the rib in the notch goes from low, higher, then the rib has bosses on the side and finally the frog is necked to meet the bosses. The arrangement of the bosses on the rib and the necking of the notch make frog adjustment fairly easy on the Bailey style plane on type 10 and later. This started out with the type 9 to lessen the amount of metal under the frog to help increase the yields from the casting process. The old frog seat had a lot of metal that could cause warping when it was cooling.
Also notice the changes at the top of the frog around the lateral lever. The first two have the cavity necked, the second two have the cavity open at the top.
140018
Finally, the first plane in this group is the only one to still have the 1888 patent date on the lateral lever. It is kind of hard to see on this one, it is a bit worn. Most of the type studies say that this patent date is not on the type 9s. If my memory is serving well, patent dates usually stayed on an item for 15 years. So this date was likely either because of left over parts or was removed in 1903. The blades for type 9 had the 1892 patent date. Type 10 is said to have began around 1907. There is a blade with just STANLEY stamped on it from this time period.
Lot of room for speculation while lifting a brew with some plane toting friends.
