Guest,
The flip up rear sight, on the barrel, tells me it is most likely a carbine configuartion. If it is mounted on the rear tang it could be either a rifle or carbine. You didn't mention a ring on the left side of the receiver so maybe it isn't a carbine. The rifle configuration was dropped after about another 20,000 were made. Your serial number dates to 1929.
You are correct that condition drives the value determination. So I really need a better handle to be very accurate. Right now I really can't do much better than someplace between $900 and $3000 probably. Pretty wide spread.
Basically I need some clarification and a better description of the condition or a few good photos. Include close ups.
Please read.
