3alarmer I’m curious on my drive train then. The bottom bracket shell does have two cable guides on both sides as well as an oil fill cap. Was this drivetrain the cheaper alternative back in the day? I take it they mass produced the same shell and then worried about what the customer wanted installed later.
I asked about the "NO" s/n because I noticed an Armstrong posted by FTwelder and my FdL both have this. I think both brands belonged to TI at the time your bike was made. These may also have been built by Phillips, as Peter Kohler suggested.
There is mixed info about the tubing being butted or plain. My bike takes a 27.2 seatpost which suggests butted. If you know your seatpost diameter (without shim) please share.
