You mean the saddle, or the bridge was lowered? I suspect you mean saddle. If the setup is acceptable and it plays well that's a deal I'd take. My D4 sounds and plays great! No you don't want to pay for a neck reset on a $400 guitar, but likely you would not need to. Impossible to say without looking at it, or better pics.
Yeah just going by shadow in one pic bridge actually looks ok, appears to have original contour from raised center section to the "wings".
And a lowered saddle is much more common than a shaved bridge.
@Sitka: in case you DO want to revisit this, or for later reference, the "ideal"
combined height of the bridge and the saddle, measured at the side facing the soundhole and at the "crowns" approximately between the A & D string, should be real close to 1/2", of which bridge height should be about 5-6/16" and saddle should be about 2-3/16".
Tolerance of as much as +/-1/8" on that total wouldn't be out of line, (my Corona D40's that tall, 5/8" total, but both the Westerlys are virtually exactly there with less than 1/32 variation) but the bridge itself needs to be tall enough to withstand splitting pressure of the saddle in its slot.
If the bridge itself is "shorter" than 5/16" that'd raise a red flag to me, to inspect very closely for signs of shaving.
In Westerly the procedure was to set the neck and then select a bridge from pre-milled stock of various heights to best match the neck angle, so the variation in bridge height is due to the imprecise nature of neck-setting.
So a bridge lower than 5/16" is possible but might also indicate a neck that was set pretty "flat" in the first place, and might shift to unacceptably high action sooner that most.
