It would be quite a trick to build a table from two numbers. Fortunately several of us have put together a few more pieces.
Until now, the way that we have dated Morris build’s has relied purely on anecdotal references to assign build dates.
With the wealth of information that Kathy has collected along with data that I was able to collect, we are trying to offer a more logical approach, one that can be used and understood by anyone with an interest in this.
In short, this table captures known and verified information and assigns a build pattern. It assumes a certain amount of revenue growth per year while tying the growth to the few milestone dates that we have been able to confirm.
There are assumptions that I made that may or may not be correct, but they are based upon the best available information we currently have.
For example, I accepted the assumption that the first serialization occurred in 1900. That is a commonly accepted opinion. Most other anecdotal dating has already accepted this as a serialization starting point. I also accepted certain key SN's assigned to known dates pre-1910 and then later in the 1910's. Those dates shaped the trend line that the serial numbers are fit to. These dates are solid so except for an error of several canoes within each of the surrounding years, the likelihood of gross error is small. I calculate about a 10% (less actually) error depending upon the method that you believe is correct
Here are several facts that we know:
1. Morris serialized 17,263 canoes. If we assume that the first serial numbers were assigned in 1900, then that amounts to a build of about 908/909 canoes per year.
2. Morris serialized 3,502 canoes through 1905 and 4,101 through 1906.
3. Morris built 4,922 canoes from 1906 through 1912
4. He serialized 9,023 through June of 1912.
5. He serialized 8,240 canoes from 1912 until the fire in December 1919.
Here are assumptions that I made:
1. Serial number 1 was assigned in 1900 (canoe SN 77 is from 1900)
2. Production grew gradually until the fire and followed the Old Town growth trend from 1900 on.
3. There were no dramatic production surges from one year to the next.
4. There was minimal revenue affect from WW1, an assumption drawn from the performance of Old Town during those years.
5. Old Town data is the benchmark for tracking the growth in canoe revenue from 1900 forward.
I generalized as follows:
• All Serial numbers pre-4,101 were built before 1906
• All Serial numbers between 4,101 and 9,023 were built during the years 1906 through 1912
• Most all serial numbers between 9,023 and 17263 were built between 1912 and 1919.
The following graph depicts the table that Kathy published yesterday. It appears to offer a reasonable view of a small canoe shop gradually increasing revenues over a 19 year period.
If you do not want to subscribe to that table you could simply assign the dates from the noted generalizations and plot production to look like this:
Quite obviously that is not a representative revenue model.
Giving benefit of the doubt, all current date assignments for Morris build have been fairly arbitrary. Until now, most assume that if there were 17,263 canoes built that you can simply divide the number of canoes by the number years and arrive at a serial number. For my amusement I plotted what that would look like and saw that (if you can ignore the milestone dates we know) that the table that I originally plotted is within 62 to 100 canoes per year from what you might expect.
Here is that table:
As you can see, this approach to the table tends make canoes that were built later look older. The flaw in this dating method is that it ignores the canoes with adequate provenance to help us assign more accurate dates.
So, back to Kathy’s point, this is an attempt to provide a simple tool that may be used to roughly date Morris canoes.
I believe that it represents a step towards more accurate dating than we have had until now. For whatever shortcomings there may be it’s certainly more visible and accessible.
Of course we will continue to refine this as canoes with provenance are located.
I am quite sure that some folks will take issue with the idea that their 1907 canoe was actually built at a later date….so it goes.
I thought mine was a 1912 or so but I am now quite certain that it was built in 1917. It still seems to paddle the same so I think I am going to learn to live with that.
As a final note, I really appreciate that Kathy shared her data with me. I learned a lot from it.
What she does not know (until now) is that I was able to verify some of her materials by through my own contact with some of her data sources.
A while ago I noted that dating Morris canoes required a real cryptic process. I don't think that is the case anymore.
This table will land you within (worst case) several hundred canoes from your actual build date.
I also don't think that this is the final word.
If we keep digging we'll eventually get a few more data points to work with and get this even closer.
For those of you that can't accept the assumption that SN's started in 1900....start the table earlier and assume what you think he was building during those years and work from there.
