The first clue is the “SON” and SONS” The keystone SON design has a short window from around 1865-71 and overlaps the SONS in 1970 then continues till Disston patented his own Glover style screw which started showing up in 1876.Looking at them both, you can see the earlier one has the single outline of the keystone while the later has the double.This is in large part due to the editor and his house of saws that will soon have this 99 in it. I don’t make nearly enough meetings but I’ve never left the parking lot sale empty handed!

Please see our terms if using more than a few dates or photos.

And who better to help me out than Mike Stemple, one of the first and most popular posts I’ve had.

The top and bottom warranted superior medallions were throwback designs featuring earlier style eagles and the middle was the current Disston medallion. Looking at the center keystone medallion and using both disstonianinstitute and past experience, this iteration of the style falls around 1870-72 but the other two look earlier to me and are often found on late 1860’s saws.

We know manufacturers often find uses for older parts and this might have been done to use up older label screws on his secondary lines.

Note the lower clip on Mike’s and it has cracks; it’s not bad but you can see how delicate the area is. So how many years between the two are there you ask?

I’d say looking at that center keystone design is the best way to date them.This could be due to the size of the saw; larger rip saws often used bigger handles.With the evolution of saws, handle refinements in general were simplified and areas that cracked were strengthened. In regards to the simplified, strengthened later handles, we often associate this as a bad thing, as the outcome is often less interesting; but in real world use, the later models have way less broken horns.So that’s where I’ll end this one for now and just point out if this type of historical look at tools interests you, consider joining one of the may tool clubs in the area. I try and stay current on three of them, the biggest being the Mid-West Tool Collectors.The Ohio Tool Collectors may be smaller in members, but for lovers of all things saws there is a never ending supply of new articles on the topic.This Taylor Brothers saw was made at the Adelaide Saw Works in Sheffield.
