Moff, ye i saw that thread. But just to keep it simple, the 12.8cm L/61 was the gun fitted to the Sturer Emil. I am pretty certain the gun on the vehcile you are building was the L/55. As it mentions in the other thread, the L/61 was just longer than the L/55.
Oh, ok. All the photos of the Jagdtiger barrel (and aftermarket L/55 Jagdtiger barrels) I had seen looked way shorter, though I guess that's because of the enormous mantlet and superstructure.
I could have sworn the Emil had the same muzzle brake as the Waffentrager, but after looking online I guess not.
As you can tell, I'm not very good at historical research
