Here are the Sargent bench plane sizes.
Along with the Stanley equivalent sizes. This includes blade width.
Also shows size comparisons between models (I’ve posted some Stanley and Record size info and thread sizes here)
The 400 series were measures off pre 1910 type except the #411 so later sizes may vary a little.
The single number series were not measures. I don’t have close to a complete set yet
The 700 series were measures off my collection as well.
