Jim,
Here's the part you did "not" know. I had a customer looking for the Model #21 you referenced in your email. I had bid on it for that customer. Several other times in the past, as I am sure has happened to other folks,I got all this crap emailed to me wanting me to click a link or whatever and screw myself with regard to my personal info. I thought that was the case here as well....HENCE: The vulgar, graphic and vivid reply. It has always worked in the past.
By the way, Jim...They are called "butt caps"..not "tops". Your description made no sense to me...sounded like you were talking about the "wrong end"???? Best, Capt. Chris
