Don, I think I stand corrected. You may be correct that .35 S&W ammo. was never intended by S&W to be produced in the self lubricating style, as patented in the 1890s era. My recollection of such ammo. goes back to the 1950s and I was probably looking at boxes of the self lubricating ammo. mixed up with boxes of .32 S&W auto &.35 S&W auto. The original self lubricating cartridges, as patented by S&W, were revolver cartridges, not auto pistol rounds, of course. Having said all that, the odds are that the next collector cartridge show I attend, I will find a box of self lubricating rounds in .35 caliber. Never fails! I'll buy it and send it to you for Christmas, Don. Ed.
