1st Gen. Colt Variation Questions

[Capt. John Fitzgerald]

Two questions;
1:  In what year did Colt introduce the hard rubber "eagle" style grips?
2:  What year did they change from bull's eye ejector to the crescent style?
Need to know if the bull's eye ejector and eagle grips are period correct when found together.  I used to have a comprehensive list that covered all of the changes to the SAA, by date, but I will be darned if I can find it now!

[St. George]

Eagle Grips were first introduced in January of 1882, and were used until 1896.

Round Ejector Rod Heads were introduced at serial #1 and were used until about serial number 65,000 - in 1882.

Cavalry revolvers used the round head until serial #114,475 - in 1885.

Vaya,

Scouts Out!
