Thanks, Darrin. I was trying to find the hydraulics thread yesterday and there were a few small threads randomly scattered on the board, but I forgot that we had discussed it in the School of the Boat section.
Drew, welcome aboard the sub forum. We're finally glad to hear someone from the Battleship Cove museum. Paul is right in that we might be able to get TRF to do a group repair for multiple boats. I doubt that they would do all of these scopes gratis. So, we should find out the cost is to the Navy to do each one and come up with an offer, such as each museum paying 50% of the bill. TRF was forced to manufacture some parts for the Cavalla scopes and each of our scopes will have a unique set of problems, but they could still send us a ballpark figure.
