Re: HOn3 Sharon coupler box w/centering spring action

You are refering to the type E couplers. They did need filing down of the shank height. The Sharon's for Blackstone cars were designed to fit in a Kadee 714 clone coupler box. The Sharon's still need to have the pivot area on the coupler reamed out in some cases. Sergent sells a reamer for just this purpose. The original Sharon's appear to have been designed to work in the Accumate coupler box, where the pivot post is just slightly smaller in diameter than the Kadee 714 boxes is. The Accumate box does have one problem that you can't file away. It is almost too wide to fit between an HOn3 wheel set. Making them impossible to use on any radius tighter than 22" radius track.

Very interesting, Dale, especially about the "stock" coupler pockets.  But remind me: wasn't there an issue with the height of these coupler boxes that required filling a few thousandth of the Sergents so they'd fit?
