Conversion Cylinder Length

[Hell-Er High Water]

Does anyone know what maximum, 38 Long Colt, overall cartridge length the R & D gated conversion cylinder for the 1851 Navy will accept?  This is the cylinder used with the original 36 caliber barrel not the one used with barrels sleeved to .357.  Thanks.

Well I got my cylinders and the measurement with cases in the chambers is 1.470" from the base of the case to the front of the cylinder.  Thanks to all who may been looking for the info.
