Tator,
I have attached my chain wheel that is for 1/4" chain that I am told is indicative of the '111' stamped on the wheel itself as pictured in Picture 2.
My chain wheel is 4 3/4 in diameter, 3" in height and 7/8 shaft.
I have reached out to a couple of vendors to include M/N and spent too much time researching what my windlass model is. I uneducated deduction is that I need a 105 wheel to accommodate my new 5/16 HT chain. If your wheel is accommodating to those dimensions, I would certainly be intrigued by your offer.
Thank you!
Cory
