A while back we were discussing the differences in the #44 Newhouse. So here are some pictures of what I think is the production line of the trap.
#1 pic. is a small pan #4, O.C. Newhouse, circa 1882-95. As u can see this trap has the Kenwood base link and swivel with 13 links of 4 1/2 wolf trap chain and the Kenwood figure 8 cold shut.
I believe this trap was the forerunner of the #44.
#2 pic. Here we have a Large pan without a pat. date Newhouse stamped #44 circa 1895-1911. I believe this is the first actual #44 that was produced. It has the Kenwood base link and swivel with 13 links of wolf trap chain and ring with the figure 8 Kenwood cold shut. Now some of the later large pan no pat. date 44's probably made around 1910-11 had the regular 44 set up with the round rod chain, connector and cast swivel.
#3 pic. This is another variation of the #44 which has the Kenwood base link small cast swivel and a #4 flat link chain. They also made some of these with the 4 1/2 wolf trap chain. The trap in the picture is a pat. date but I have also had one without a pat. date.
#4 pic. This is a pat. date Newhouse stamped #44. It has a round rod chain connector cast swivel with the 13 links wolf trap chain with the ring. I believe most pat. dated 44's came with this setup. As u can see this trap has a split jaw post which puts it in the 1916-18 era.
So this is my take on the #44 Newhouse chain set ups.
