Was Lincoln’s coffin opened in February 1866 ?

[L Verge]

Would records still exist with the caretakers of the tomb today? Surely there were official notations on such things as repeated openings of the coffin. It's been several years since I read Stealing Lincoln's Body; does Thomas Craughwell make any mention of in that book? What about Tom Schwartz? Does his expertise extend into subjects related to the tomb?
