Yes, that's what the "LW" in the serial number means.
I don't think so, because Colt frame having M1911A1 US ARMY with serial number 1152033 was produced in 1943 contrary to the fact that colt commander models production were onlystarted in 1949.
If you have a steel frame model 39-2 it was made in the year 1971.If you have a alloy frame,and steel slide then your model 39-2 was made between 1972-1983 without a serial number provided.
An alloy bike frame is made from a mixture of metals, while an aluminum bike frame is made solely from aluminum. Aluminum is a type of metal, so an aluminum bike frame is a specific type of alloy bike frame.
Go to proofhouse.com to date it. You will be in mid to late 60's time frame.
not familliar with pk but the colt with just a k notes it has an alloy frame that should seem heavier than others
The Browning Nomad, a .22 caliber pistol, last featured an alloy frame in 1980. After that year, the model transitioned to a different material, which marked the end of the alloy frame versions. This change was part of Browning's efforts to modernize their firearms lineup.
Made with an aluminum alloy frame
The specific bike frame model used in this bicycle is the "Aluminum Alloy Frame."
The serial number is on the frame.
The Challenger II has an all steel frame and the Challenger III has an alloy frame; I don't know what the alloy is.
Hard to answer without the entire serial number..... it should have LW after the serial number or CLW before it for post 1970 guns. If it doesn't it may be a non-colt frame... Ed
colt combat commander has a steel frame, the regular commander has one made of alumimum. this is the main difference.
