Hi Bill,
As Ed has said, we would be very curious to see photos of your piece and accessories.
Typically, a Swiss luger will have a 4-3/4" barrel and be chambered in .30 cal (7.65 mm); yours may have been rebarreled at some point in time.
If your gun's entire serial number is "45"...that would be most rare. Is there a longer serial number which just ends with the last two digits of "45" ?
The serial numbers of all the Swiss luger are well documented in several books...let us know the entire serial number and we can look it up for you...
A 32-round drum magazine (aka TM-08) belongs with an Artillery luger. If this TM-08 is real (i.e. not a repro) and in good shape; they have been selling in the $ 1000 to 1300 price range...so you might want to sell that separately.
If you need help posting photos, send them to my email address, listed below, and I would be happy to do so for you...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
