Hello John,
The 24th. edition of the Blue Book of Gun Values, on page 929, lists a 1920's commercial luger at 98% 'original' finish at $ 825.00 plus a 25% cost premium for a 9 mm caliber.
The $ 1500.00 asking price you mentioned seems very, very high for a plenitful and easy to find luger from the 1920's...
Cannot tell for sure from the photos, but this one might be a refinished piece (rather some parts...), so value then drops...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
