Crackstock,
A few weeks back Tip only had TN stocks inlet for a Siler lock, however he was working on a stock pattern inlet for the new lock he has. Looked on the outside much like a Chambers Late Ketland. I believe the pan bolser was different and the internals were different. I don't know much other than that about the lock and he said the stock would be availible soon. Like I said that was several weeks back. It will be a pre-inlet alternative to the Germanic looking Siler.
All the other stock suppliers mentioned offer a stock without the lock inlet so you can use what you want.
