Ok.. It stood out in a bucket of sockets but it just looked like a big ol' universal 3/4" drive S-K Tools socket extension. I seriously looked up the S-K number 47148 and was dumbfounded when I kept finding a 1 1/2" socket for the picture. I couldn't figure it out and just stared at it and had a couple more beers. Sometimes the obvious isn't so obvious.... Then it came to me - Oh S#%*! Someone broke the universal and then found a 1 1/2" S-K socket and welded it on to fix it.....
Now the question comes to my mind is "How did they break it in the first place?"..
******Updated Info***** I got in touch with the person who sold this to me and he fully remembered the item.. What happened was he was working on a D41 (semi or tractor, I didn't ask) and there was a frozen nut/bolt they couldn't get off so he stood on the breaker bar and bounced up and down and then he heard a big crack and though he was going to be dead... Snapped the universal... and then had to weld the S-K on to finish the job.. The nut/bolt finally loosened up :).. FYI he looks about 6 foot - 220 to 240 pounds...
This universal extension is 5 1/4" long and weighs 2 pounds 10 ounces.
