looks like an alphabet commercial wich were the most produced luger there was I believe.
with the suffix m on the serial (they started with 4 digits 0000-9999 then once they past four digits they restarted the numbers and added a letter differentiating ranges of numbers instead of just starting at 0 and going to 100000000000 for instance)its probably between 1922-25 for the year of production. there is a sticky in the commercial section wich could help you date it further. military guns have the year or a code for the year they were built stamped on them as well as obvious and plentiful serial numbers on almost every part.

( it has a nitro proof wich is a tipoff its commercial ) crown n

if all parts internal and external match and its original finish worth maybe up to 800 the condition its in on a good day ( maybe).
any nonmatched parts or refinishing 4-500$

the caliber should be .30 luger
unless I am way out in left field but I found this one in the database with a fairly close serial: 9227 m alphabet c/N upright MADE IN GERMANY .30
