In one of the posts I remember seeing the Saddle Bolts/Studs were different for the early BSAs to accommodate the Horn.
Please validate my understanding

Correct Pratap. The left side saddle spring stud has a flat with a hole to hang the horn from. Ron

Yes this is the left hand bolt, other side has a standard hex head I think?

Did all of the WM20's have horn in that location, as I have seen some mounted in front between engine and frame.

Kim,

No not all M20's had the horn located there. According to the historic facts, the horn was relocated sometime in 1942. I don't know the reason, but I have heard, that the horn couldn't be heard when the rider was wearing the long mac, whether that's true or not.
