MP Sniper - you have the "Premier" model - standard was 3", 5 shot .32 S&W (the short one) with nickel finish and black, hard rubber grips. They were offered with the following options:
barrels: 2" (Bicycle Model), 3", 4", 5" & 6" (all but 3" are scarce, 6" is rare)
finish: blue (scarce) or nickel
calibers: 5 shot in .32, 7 - shot in .22 lr (scarce)
grips: black HR, hand grooved walnut (rare); mother of pearl (scarce), ivory(very very rare add 100%).
Made from 1895 up to mid 1940s, in at least 3 models and several variations within each model series.
There were over 500,000 made during this period. They were popular, well made, middle price point SD/pocket pistols, during that period. Some hundreds were bought by the US Gov't during WW2 and issued to OSS operatives as a concealed carry weapon.
Most of those seen today have been well used and as krs mentions, many of them have been shot loose.
I have several that are as new or in excellent condition and these are solid, very tight and index/time perfectly. By today's standards, they fall a bit short of the mark - but I know one retired Cop from Philly who carries one on a regular basis for his CCW weapon - I'm not advocating this.
Current valuations range from around $35 for a parts gun, up to around $300 for one in excellent condition with a 6" or 5" barrel, in blue finish. The bicycle model draws quite a bit of interest amongst collectors because of the short barrel and typically sell between $200 and $300 in excellent condition.
If you supply the serial number - I can give you Model, variation and approx. year of manufacture.
