Re: [SergentEng] Coupler not working properly

Hi Ed,
I looked back to see when you placed your last order. I’m not aware of any type of casting problems that existed in that time period. I think the best way to diagnose this is for you to send me your bad couplers and let me dissect them. Don’t go crazy on packing materials. A plain envelope with the couplers taped to a piece of paper usually works just fine and is cheap to mail. Send to Sergent Engineering, 7620 Crestland Rd. Knoxville, TN 37938. I can get them headed back to you in a week or less.

I do remember the problem you describe.  I thought the coupler hole elongation problem was just with the "fancy" couplers.  Mine/ours are the type E.
I'm also not seeing how an elongated hole would cause the steel ball to drop behind the coupler knuckle casting. 
I look forward to Frank discussing the matter.
