"I've seen them on EBay go for as little $150.00 and as much as $350.00"
The 'blue' book or tenor guitars? And what's a 'George Gruhn'?

" Whats to tell."
Considering that I still know not much about this specific modle, anything else anyone can tell me is appreciated as well... like why the 'date' stamp appears to show 1902???? Was that an attempt by Harmony to make newer insts. SEEM older?
