It has occurred to us for many (20+) years to offer a deal to return 312 to the WW&F. A little perspective:
For Boothbay Railway, which itself was founded on the memory of the WW&F, this car represents their one connection to the original. They have several SR&RL boxcars, but as their only Wiscasset car, they've been led to decline all previous offers. That doesn't mean they would again, or that the offer of a Bridgton trade may make the difference; it may. The point is though: just because it would "complete our collection" doesn't mean it holds no value to BRV. They have made efforts to preserve the car and, I believe, have further plans.
We'll have a substantial fundraising and restoration effort into the Bridgton car. If we traded, we'd be doing it again with 312. Maybe that's ok- but I wouldn't presume so without getting the 67 project's stakeholders on board (those who donated; those who worked to raise the money, those working to restore the car). All in all it may be best to stick with the plan and adopt 67 into our family.
Maybe there'll be an opportunity to return 312 to the WW&F at some point. As usual there's more to the story than meets the eye, so it's important to remember the consideration made for a vast number of details with such deals.
This idea was lightly discussed last fall, and set aside due to the effort we'll have into 67. Anythings possible; at the moment we're excited to return 67 to service.
See ya
