That's also 131. She was the only one that had that step welded on the front. I modelled my buddies 504 Tiger after the 142 and took some creative license with leaving the feifels gray. Of the 11 504 Tigers in Tunisia, only these 2 had numbers shown in the photographic record. It's not quite enough evidence to suggest that the first 2 tanks in each platoon were Tigers and the others 2 PZIIIs. This is how the 1Kp of the 501 was organized while the 2Kp Tigers got the odd numbers. This all changed once they merged with Panzer Regiment 7 and the 504th.
