Thanks alot Rivetcounter! After searching a while, I finally found it. Best part is that a forum member posted a pic of it before it's capture. Also these improvised exhaust extensions had 4 vent slits facing the turret on another Tiger (whether there were matching ones towards the rear is unknow.)TheTiger 100 had a different variation from the others (taller)I suppose the four slits on the Tiger 100 exhaust extensionsis unsupported, but I think I will add themas ashot in the dark ormore uniqueness and sacrifice a bit of accuracy.The new information that I've acquired now makes me second guess it's use with the fording pipe since it has those vent slits. I'm wondering if they were used to prevent snow from building up into the exhaust when the Tiger was stationary for long periods.....maybe before hinged flappers for the exhaust were added to the tank....or maybe these suppressed sound or fog when heat hit the cold air giving away their position? I can't think of any other reason, don't think a collection of snow building up in the exhaust pipe, fog, or soundwould be a good thing. Good stuff on that site.
