How many holes for a headbadge are there?
The seatstay cluster design is similar to some I've seen on Malvern Star
bikes. Not sure that they used headbadges I'm used to seeing the raised
stars on the headtube.
Another popular brand was Flash, not sure how to ID them but
they also used Nervex lugs.
It appears to be a nice frame, low end stuff usually doesn't
have serial numbers.
Can you measure the seat tube for seatpost size? I'm wondering
if it's Reynolds tubing.
