ok looking at the lid hinges mine is a late can so more than likely it never had a brush holder. what it should have that it is missing is the wood block at the bottom to hold the scope. not sure how it was removed. the horse hair lining is almost perfect. maybe it broke and was removed is pieces.The late scope (ZF41 type2 and ZF41/1) will not fit early can, since the lid of early can is a bit shorter than the late.

And the late ones do not have the brush tube.

I believe the brush was omitted in the late set.
