Visalia Saddle Maker Mark???

[Outakuntrol]

I'm looking for info on this old Visalia saddle. The maker marks stamped on the rear of the seat, my question is the "Y 5" that's tooled above the makers mark has me wondering if this could have been custom made or standard. The saddle is in bad shape, even has mold.  Still for me a nice piece to add to my collection.  Thank you

Without examining the rest of the saddle and comparing with period catalogues it is impossible to say if it was entirely custom made or just a personalized standard model
