So I may have a lead on the correct "182" for this pit.
View attachment 1881952
The part map calls for a 1:35 scale Tamiya King Tiger. But it's not, the Tamiya part is way too large and has the wrong details (as we sort of know already), but I ~think~ I have found the correct kit. It's a bit obscure but I have one being shipped to me, the problem is the Canada Post strike and me not knowing when it will ever show up.
When I get it and can properly compare, I'll post more information.
Unless of course everyone already knows that the correct kit is and I'm just being redundant.
