That makes plenty of sense now you say it. Let's see what a torch light discovers.
Have you try blowing through with a air line ? maybe only the inner cables goes through the middle off the top tube and outer is only at the front and the exit..my guess
I'll have a check with a torch tomorrow, but it sounds like internal stops are likely as it goes.
