This post’ll be no help whatsoever, and it’ll probably ramble on a bit (due to my age), but I knock about on an generic-steel MBK road frame of similar vintage.
It’s currently SS and just used for nipping into town on, with it’s scruffy appearance and oddly mismatched wheels, it’s not going to attract much attention.
… but having ridden it a bit more of late, I’m now on the cusp of having it resprayed, and dropping in a new groupset and some decent wheels; dunno if I missed it back along, or if I’ve changed over time, but there is very definitely *something* about the way the frame rides that’s drawing me go back to it.
