I will try and guess what your wanting to know, first I'm guessing you are talking about old Colt percussion (ball & cap) revolvers converted to fire metallic cartridges. If so, and they were accutally converted buy Colt then yes most models of Colt conversions had the loading lever removed and replaced with a ejector rod, with the exception of the Colt Thuer conversion models, which could be changed back and forth between ball & cap and cartridges. It would still have the loading lever attached not only to be used for loading balls into the percussion cylinder but also to seat the special tappered cartridges into the conversion cylinder. Another thing the loading lever was used for, to reload those special tappered cases as the inside of loading levers end was threaded to accept the primmer punch. BTW it was a complex system which didn't go over very well, so when the Rollin White patent expired Colt didn't waste any time converting their large inventory of percussion guns & parts to use bored-through cylinders. Now there were also conversions not done by the Colt factory, also known as blacksmith conversions and they could range from being crudely done to nearly appear like Colt had done it themselfs. Hope this helps, LM.
PS. A very good source of information on Colt conversions is a book written by R. Bruce McDowell, "A Study of Colt Conversions and Other Percussion Revolvers" It goes into great detail covering all models of Colts different conversions along with some expermental guns.
