naw .. threaded saddles, top load only is all anyone needs to identify as an early edition Hwy 1 (number) with just a body pic ... OP is more informed than he thought, calling it correctly as a 1, and not a ONE ...
Edit to add: early AmStands from 95-99, and AmSeries 2000-2007 were all STB with 3 hole mount bridges, with the coarser spiral saddles ... all Hwy 1's used the finer threaded saddle bridge with a 5 hole mount pattern ...
... also, if this was an '04 AmSeries, it would have the S-1 switch on the volume knob, unless of course it was removed ...
