Last weekend I found this 29K (built in 1905) and figured the tag says 29 K.S.V 3 - so obviously a Special Version (or variant) of the 29K cobbler machine.
The only obvious difference compared with a 29K3 is that the 29K S.V. 3 has two threaded holes in the lower arm. This most likely is for attaching a binder attachment. I have no proof for this but I guess the threads are for a binder attachment.
I just wanted to share some pictures because there are not many of them around and even on Nee
