I would definitely be interested in hearing of any experiments with this.  Thanks for asking.

Good evening gang,

Q: Has anyone experimented with doing slotted knuckles for the early knuckle coupler era and, if so, what were the results?

For those of you unfamiliar, these are knuckles with a horizontal slot cut to accommodate the transition period from link and pin to automatic couplers at the turn of the 20th century. For the Sergent line of products, these would most likely be applied to Sharon couplers. 

Thanks,
