You can get a folder from your local dealer or off of ebay. As for key dates 1894 is high and the 95 which was a proof only. There are some others that are semi keys,90o, 93, 93o, 95o, 95s, 1903o. Plus all the ones you stated.
I think you said you got the Red Book the other day...that should have everything that you would need to have to know what the keys are.... Speedy
