CallumThanks for the help guys. I will give that forum a try to see if anyone can confirm if it is the "Z" model or not.
With regards to the wedge. I do have the original blade and did notice it is much thicker, so I tried to replicate the angle when shaving. But the wedge sounds like the perfect solution. Am I removing the spine and using the spine as a wedge? So a spine and then a new blade with a spine on top of that? Bit like this https://www.badgerandblade.com/forum/threads/shovel-head-razor.469507/
Sorry if that's a stupid question.
It is so long ago that I did it that my memory is a bit hazy. Think it was a 1/2 spine but am sure someone will give a definitive answer.I used a few oldies but passed them on, as I have enough of various types to keep me busy.
