If you are looking on the Bay, some 110 models of Sakae(SR), Sugino and Takagi came as doubles with the 74 holes drilled for a triple. Type in 110 crank and look at the back of the crank to see if it has the 74 holes like the Sakae SX I listed above. I know the following cranks all had 110/74 triple options.
Sakae SX, CR
Sugino VT, AT
Shimano FC-6206 and other models
Takagi AID and other models
