The 4115 Whitney seems ok. Coach
did make some bags in the US at an H plant, and even a few sample bags had that code. Plant codes were often transferred and with only a few exceptions like the Italy plant could have been used in more than one country. The "M" plant code was bounced around more than a tennis ball at Wimbledon. Figuring out the dates for various plant codes is still very much a guessing game and NOT for the faint-hearted.
The red one MIGHT be ok. Usually I don't recommend buying any mid to late 1990s bag with any serial number that begins with "J" since it seems at least half of them are fake or questionable. This might be genuine but I don't own a real one to compare it to.
