I assume the gun will have the Lefever adjusting screw? If so, would that help alleviate the need for the doll's head, if that became a problem to manufacture? Personally, I say keep the doll's head if at all possible. Lefever's are as highly regarded as they are not just for their aesthetics and handling, but for their ingenious engineering. Their strength and functionality are one of their main selling points. With that in mind, chrome-lined bores and tubes seem superfluous and somewhat irrelevant. Build the gun the right way and there will be no need for them.

For the record, I'm not a big fan of the stepped side plates either. Long, thin barrels, splinter, scaled frame with 16/20 barrels, and Lefever engineering. Voila! You can't go wrong with a formula like that. Add the 12b later after it takes off.
