I have recently purchased a colt 45 and I am looking to find some info on it. It is a duo tone finish, on the left side it has Colts mfg. engraved along with some dates,Apr20 1897,Sep9 1902,Dec19 1905,Feb14 1911,and Aug19 1913. On the other side it has a star with a banner under it, there is something written in the banner but I dont have a magnafying glass to see it. There are also the words EXERCITO BRASILEIRO and under those words it has 1937 which I assumed it was the model number. The serial number is B205XX. There is also another number on the barrel it is 4589. If any one can help me on some info it would be appreciated.
