I'm pretty sure it is not Argos, or at least I have not seen them using these lugs? Interesting seat stay tops, anyone has any idea of what it could be?
Unfortunately no pics as not mine, spotted on FB for sale and was intrigued as never seen twisted seat cap as on thisNeed a closer up look/photos. Any serial no. on the BB?
But it could be an Argos - if you supply your own lugs and tubing they'll build a bike for you.
Forum user 'Nob' recently gave Argos a NOS columbus Air tubeset and they built him a TT bike from it.
