Hi Jeff,
Thats probably correct as the Ayala blades had virtually the same type fuller and if I am not mistaken, Ayala used the 'Jesus' "Maria' on opposing blade sides, I could not identify the mark used as I recall as it was too encrusted. I believe Ayala was one of only a few Toledo smiths who used that motif . Again, Marc will have the final word
All the best,
Jim
