Same here. I test fired an original type 2 Bing using a 1917 LP08 with no problems whatsoever, even fully charged with 32 rounds, no feeding issues whatsoever.
I even loaded it with 32 .30 luger rounds and shot them from a Swiss 06/29. Neither the pistol nor the ammo were meant to be used with that drum and both functioned flawlessly.
Bing knew how to make sheet metal toys, that is a fact
