Well, that sounds better than the Jurassic reference! I think.
As of the '70's (or maybe even the '80's, I don't know when the fancy-schmancy optical thingy's were introduced) what y'all are quaintly calling the "old string method" was not "field expedient" it was simply "THE boresight procedure" and the only known way it way it was done. There were a couple of variations of sighting down the chamber from the inside. One involved removing the firing pin mechanism from 90mm's (I believe) and there was also a round template thingy with a female receptacle that could receive the objective end of one side of a binocular that you could stick in the open breech (better method, less squinting) and both had the advantage of letting you just speak to the gunner so he could lay the crosshairs of the string on the selected right angle.
Then the gunner aligns the reticle and you have your rough sights set and you're ready to go to the range and bust some caps for zero.
Joe D. and Rob can clean up an details I've managed to screw up....
- SFC_Jeff_ButtonI saw that M48A5's and M60's used Pye-Watsons according to previous posts. I'm assuming that these two M60 barrels had these "tick-marks" at 12, 3, 6, and 9 o-clock for back-up, field expediant, string cross hair markings. Were the strings just simply attached with 100mph tape?
