Wow, that's a tough one. Coppercoins says #3 is d/d/d. Yours looks pretty close. What does your rpm book say? Oh ya, by the way, I tried looking for that book and you're right...you can't find it anywhere. I found one on amazon for $155, crazy. I'll just keep my eyes open for one. Nice pictures though, is that through a loupe?
Yep, you got it right... I goofed a little bit, it is a DDD. Try as I might, I cannot get a good picture by putting a loupe in front of my camera lens. Instead, I opted to let my hubby buy me a nice camera that does a pretty good job of photographing... despite my ineptness. I took the pic with my Canon PowerShot SD 850 IS, Digital Elph which has a 4x macro capability. Afterward it goes into the program supplied with the camera, and from there to my pictures. Then I grab the pics from my pictures and put them in my Paint Shop Pro v.7 and edit, i.e., magnify greater, size and crop, and use the gray scale feature if needed to improve the pic for easier identification. All of this is trial and error... many trials may be necessary to find the error... Oh my, I think I just made a joke/pun...whatever. Thanks grnwavdav. jeankay
