Joe,
You are correct - Sheepscot made some of the first points and frogs; I volunteered to make frogs and points in Baltimore, both for something to do while "away" as well as take one burden off the busy guys up there, AND I had access to a larger milling machine than what had been available at Sheepscot. Jason still has the fixtures, wedges, etc. to hold the small rail on the mill bed at the proper angles to make the tapered cuts, so that is why I sent the one unfinished rail back north for completion.
