K&M saddles - are they all made the same?

[Christmas Crumpet]

Just a musing I had this morning about adjustable saddles. Are they all made exactly the same and then a different gullets put in? So a narrow saddle and a xw saddle would be made identical with the same tree and then the correct gullet put in or are they made differently? Hope that makes sense!! I'm hoping they are not made identically because a narrow saddle which then has a wide gullet bar put in would surely be more curvy?

Well yes they have a few different tree styles - standard, high wither, cob

But the gullet bars go from N/M through to XW or thereabouts and it just changes the angle of the head and nothing else.

Pretty much all of the changeable gullet saddles are the same, it's not just K&M it's right through to the expensive European saddles that are adjusted on a machine
