Shark's Tooth Tuners On A Martin?

A couple years came with them... I have a bergstrom martin with shark tooth tuners as well and have seen others..
 
My soprano has the shark fin tuners...although I thought it was built in the 50's.
Can't tell you if this is the original configuration. Perhaps a UU Martin expert can verify ifn they were so equipped for a time?
Thanks a bunch.
 
What a waste of good Harmony tuners. :)
