yes it is
40cm = 0.4m
400mm = 0.4m
Your western field model 04M-489B was made by Mossberg.The Mossberg model 50 is the same firearm.These parts should be found at Numrich gun parts corp.They may be found on the web.
according to the cross reference sheet I found it is the same as the westernfield 04-m 390a model
Mossberg, it's the same as Mossberg 26B or C and was made around 1940. Good luck.
As far as I can tell from my research the 04m-497a is a version of the Mossberg 42. I've found a clip on http://www.gun-parts.com/mossberg/
50-200 USD
I cant find retail data on this gun, but it would probably be correct to say that the differences would be in a plain stock vs a checkered stock. Also, the finish will be better on one over the other
I believe what you hae is a Mossberg model 42
There 100 centimeters in a meter. So if you put the four in the hundreds slots you could say 4 cm = .04m.
The scale "4 cm = 1 m" is a factor of 1:25 (1/25th scale). 1m/.04m = 25
Type your answer here... These guns were manufactured by Mossberg for Montgomery Ward (Same as Mossberg Model 26 b or c) between 1938-1941. They have proven to be nice, tough simple little American .22 single-shot rifles.
Your rifle was made for Wards by Mossberg, and is their Model 26B/ 26C. They were made between 1938-1941.
Your firearm was made for montgomery wards by Mossberg and Sons.It is the Mossberg model 73C.This is priced between 40-85 dollars on today,s market,dpending on overall condition.
