i love you guys! where else in the world could i get this info!!!!!

i just got home from slaving, but i will check out my grips tomorrow, although, at this point, i am sure it is the long frame with the "low" diamond.

goony, that is an absolute beauty! mine is not perfect, but it was the lowest serial/earliest airweight i had ever found, and the only chance i had had at one with the bug, so i picked it up. it is very interesting that ours are that close together. i have about decided that the little screws were somewhat scattered throughout the earlier production, especially popping up frequently in the 27000-29000 range. you may very well be right that they actually STARTED using them somewhere on up in production, as opposed to using them right from the beginning.

as i said before, about the 24000 range is the lowest i have ever had any contact with.

again, i appreciate all the valuable info and pics!!!!
