My #3 Target (top break) revolver is chambered in 38-44. It might be possible to shorten the 357mag. brass or use the 38super brass?
captsnapshot,
I can't actually help out as far as locating some Original Brass, but I can offer you some info that may help until you do!!
First of all, there's no need to shorten 357 Mag Brass whatsoever!! Reason being, the Case Length for Original 38/44 Target Brass is 1.475 compared to 1.290 for 357 Mag!! The only thing you have to remember is to seat the bullet your using (Depending on Nose Profile) deep enough not to extend past the front face of the cylinder!!
Secondly, the only Brass that has a long enough Case Length to build Cases to fit the chambers of your 38/44 exactly are 357 Maximum Casings!! Drawback is...they are hard to find as well as expensive & still need to be trimmed back about .115 to build duplicate 38/44 Brass!! Of course I'm referring to seating the Bullet flush with the Case Mouth as I'm sure you already know the Originals were!!
Last of all, you didn't mention if you knew the actual 38/44 Target Cartridge Dimensions so I'm attaching some photos with info you can download that may help should you stumble across some 357 Maximum Cases at a reasonable price!! There's also one there that shows what an Original Cartridge looks like when chambered just in case!! Anyway, hope I've been of some help even though I wasn't able to point you in the right direction to find any Original Casings...Sorry!!
