"The "third pattern" for 16s Illinois seems to be restricted to the "Bunn" grade consisting of 17jewel and 19jewel movements, so we move on to The Fourth rayed pattern.

The 'Fourth Rayed Pattern' is the most common pattern for 16s Bunn Special movements. The changes are in the markings and some changes in the ratchet wheel styles".

"We continue with the Fourth Rayed pattern, but now The movements will show a change in the movement marking. For an unknown reason, TEMPERATURE was now abbreviated to a marking TEMP. Other features remain the same, though there have been observed variations in Ratchet wheel designs. The balance cock retains the "checkerboard" pattern index". There are a couple of anomalies in the list below... 3030210 has the screws facing up on balance jewel setting, the rest of the observed example have the screws down (screw head visible) more on this later. Also observed movement 3030934 IS A 19J Bunn grade model 9, from 3030001-3031000 run listed as 21J Bunn Special. Further research will be required for these examples."

We continue with the Fourth Rayed pattern, but now we see an additional change in the marking. The index on the regulator now has "slash" or "straight lines" instead of the checkerboard pattern. This is shown in the images on the left of the page. On the Right of the page, we see what is considered the final change for the Fourth Rayed pattern, TEMP marking movements... the elimination of the BORDER around the Balance Cock. The Balance cock retains the "slash" or "straight line" index markings. The differences are noted in the images below the movement image as close-ups of the Balance cocks. This final change seems to take us to the last run of movements and the change to the Sixty-hour mainspring models.

Continuing with the 21jewel Bunn Special Fourth Rayed pattern in Model 8 (hunter) the next changes are shown below. Illinois changed the marking on the plates. Instead of the previous marking spelling out 'SIX'in the adjustment marking, the NUMERAL '6' is now used. Even this has a variation as seen below. One grouping of movements with the numeral '6' located on the LEFT, and a grouping with the '6' on the RIGHT. You can also see that now the balance jewel plate screw heads are visible.

Meggers descrirbes in his book a SIXTH pattern...being a Fourth Rayed damaskeen pattern Model 9, 21 jewel, but having an ALL OVER GOLD or GOLD FLASH to the movement after the damaskeen. At the time of the Meggers-Ehrhardt book, one example had been observed and is on the cover of the Book.. below is a second example. Complete image documentation has been performed on this example with all matching serial numbers and the flashing has been throughly examined.

Now we have 'THE' 21 Jewel Bunn Special Pinwheel (Seventh Pattern) Open Face, Model 9, Circa 1919. This pattern seems exclusive to serial number run beginning at serial number 3,491,001. As best known today, production of between 40-60 pieces seems possible. Only 1 physical example known so far, 3,491,012. Also known is a Jeweler's Sales Ads for this exact pattern. Example shown in the ad is 27 numbers higher, 3,491,039

This Pattern was designated 7th Pattern by Michael Chamelin (owner) after allowing Bill Meggers to name it, out of respect for him and in appreciation for all his hard work and research on the Illinois Watch Co. Bill was furnished images of this watch shortly after its discovery.

Designating this pattern as Seventh Pattern would continue forward in chronological sequence the patterns that he had already previously designated and named, and presented in the Illinois Book for 16 size Bunn and Bunn Special:
1st Pattern, Bright Spot
2nd Pattern, Fishscale
3rd Pattern, Sunburst (17 & 19 J Bunn grades only at this time)
4th Pattern, Rayed
5th Pattern, Interrupted Rayed
6th Pattern, All-Over Gold
7th Pattern, Pinwheel.
