I agree with AnimalChin. That is a 'Senator' from the mid 1940's and i know because i have one from 1944. That 8AH movement is a bit fragile. I've got two spare parts movements here both with sub-seconds intact and the posts are very short. The sub-seconds hand in your photo seems to be positioned properly so is he sure its a broken post? Personally i think if he was advertising it as a 1910 model I would be questioning the vendor....
