I have a two of each of these items so I am keeping one of each and selling the excess rings.
I have the following items. I am slapping in some prices but feel free to email me with offers or if you need to see pics. 24t Inch Pitch ring - no name, appears practically NOS. plating excellent. Fits Williams crankset. Say $40 shipped.
52 standard ring - fits Williams crankset as well. Not shiny, dull finish. No name but there is engraving on the back that read dural forge Guar??? unreadable to my eyes. The lettering circles around a wheel-like engraving. Appears to have plenty of life left. Unsure of year, it came with a Williams crankset that dated to the early 50s. Say $25 shipped
I have several standard rear cogs as well, once I sort through them to determine type and # of teeth I will be posting them as well. They are quite old and came on a 30s hub so keep an eye out for these coming soon.
Email me with any questions. Thanks for looking.
