Replace verticle bubble in old spirit level

Hi, I am going to try to repair my mums very old spirit level (it was her dads and he passed away a few years ago), for some reason this level means a lot to her, we had a handyman over doing some work and mum walked outside and noticed him hitting the top of the level with a hammer (trying to hammer something down) she stopped him but then noticed the vertical bubble on the end had no fluid in it anymore (must be broken), I can see how to take off the middle metal plate to adjust the centre bubble but how do you get the vertical end bubble/vials out ??, there looks to be a big brown plug in the end inline where it is but I am not game to starting prying it apart, I really want to have a go at fixing it to give for her birthday but don't want to break it, I will post a pic of the level and hope to god someone has some insight, thanks again for taking the time to read.



PS if I am in he wrong section I am sorry, maybe admin can move it to the correct section.
