Aw yes the changes. I went crazy with all of them. When I first stated that I was going to convert a Early Tiger1 into the Initial Tiger1 142 of the 501 swathdiver wished me good luck, but with his help and hours upon hours of research it was finally done. I did not know how many changes there were.
Like rivetcounter said they changed almost on a monthly if not weekly basis. That's not counting the field mods.
I am doing a Panther D which is a little more straight forward yet still a lot of changes.

dedmonwakin is in for some fun, but is off to a good start. And once done will have a unique Tiger1.

You can see the complete 142 build plus my panther D and others here at the DAK sight. Lots of great builds and info.
