I’m not interested in buying it, I was just curious. Juvela, that is quite the detailed assessment. Thank you.
While no expert in Schwinn’s imported or otherwise I saw the decal from the crankset photo, the head badge holes and the fact it had been rebuilt using a modern bottom bracket strongly suggesting English/ ISO threads, it does bear a strong resemblance to many of the Garlatti frames provided by a quick google image search.
Edit: for what it’s worth the seller sent me this photo. Clearly it’s no Paramount and to the sellers credit he never claimed that it was.
