What changes what this is worth
Same catalogue number, different money. These are the attributes that separate two otherwise identical 1794-TB2 units — check each one before you quote or bid.
Series letter
Series letter on the label. Later series are not always backward compatible and sell for more.
Printed on the label, usually right after the catalogue number, as "SER A".
Tested or untested
Tested / as-is / new-in-box. The single biggest multiplier on used price.
Not on the plate. It comes from whoever pulled the unit, and it moves the price more than anything printed.
