It would be a shame to destroy the originality of what by now is rare and moving towards historic. I would just run it up at 110v, possibly via a variac and see if the transformer gets hot. Older quality equipment did not suffer so much from the need to cut corners with the pricing and production cost. I have a number of such 117v items and I tend not to worry too much.
