Looks like a pretty obvious hack job to me. I've never heard of a Lamber t inch pitch ring. Never heard of any sort of Lambert track ring for tha t matter. The earliest Lambert rings appear identical to TA Cyclotourist and were probably made by TA. The later ones have those circular holes and may have actually been made by Lambert or contracted to someone other t han TA. But AFAIK they were all 1/2 x 3/32.

This popped up over on the bob list, anyone have the sure answer on this?
Tom's son has a viscount with a skip tooth lambert branded chainring, first
three pics in this set:

I sez its a production item that probably exists to ease shifting like an e arly version of ramped cogs and chainrings, like the shimano skip tooth freewhee l cogs. Any confirmation? others seem convinced that it is a hack job with files...
Secondly to answer Matthews question:
I have found lots of skip tooth "track" cogs to be very oddly threaded, I am guessing they were either for specific hubs, or are actually coaster brake stuff. I put up some photos in the same set of a variety of s kip tooth stuff in my bike dungeon, I know the new departure coaster brake cogs are for coasterbrakes, but I am not sure what all of the track cogs are for in the track cog pics, I am guessing some of those are some odd brit thread and ot hers are for coaster brakes and one threads for sure on a normal threaded track hub. So I think the non-offsett stuff might be more likely for coaster brake hub s.
Finally there is a nice pic of my NOS regina Blocchi chain and box it came in. I think I like the box more than the chain, but I am not sure. It might be that I just like chanting Blocchi as I ride around.
