If you put Freddie Grubb or any other known frame builder's name on something they didn't build, you'll constantly feel shame when people draw attention to it, regardless of whether they say "Nice" or "Fake". If you make something up, people will either say "Never seen one of those before", to which can honestly say that neither have you, or they might bluff it with some comment about how their earlier ones had different lugs etc. in which case you've won.
