wedges what would AK and AJ mean ?

[John Cornelisse]

There are a few wedges in my collection, they are marked with AK and sometimes even other markings can be found like AJ.

It looks, that there might be no difference between a wedge S5 and a AK wedge...

The last wedge does not have the lid, that will change the position of the wedge...

here some pictures








The AJ wedge  has two sets, 8AJ  and 7.5AJ, I suppose this wedge was meant for casting typewriter...
