    the bearings in those BB are held in a cage, its common for the cage to rust and disintegrate causing the cranks to flop about. you just need to replace that bearing cage and all will be good again.

    specific tools you will most likely need - crank remover, a lock ring tool to get the lock ring off, often the tools that come with old bikes that everyone has kicking around somewhere will have the lock ring tool on there. big adjustable spanner to undo the cup. just clean it out and put back together.

    i would use the tyre thats on there, doesnt look like theres anything at all wrong with it. even so 27 1x1/4 tyres are easy to get still, i bought some a couple weeks ago dirt cheap. fine for a budget racing bike like that if its just for rolling to the pub on etc premiercamping.com/27-x-1-1-4­-road-bike-tyre/?catargetid=520002630000­002196&cadevice=c&gclid=CO7vpvHF5r8CFQH3­wgodjTYAqA

    you could have it all done for under £10 and shouldnt take you long to sort out

    take it apart and replace the broken bit. its usually obvious which part is broken. either get new parts or use a donor hub.

    they seem daunting at first but are actually pretty easy to work on.

    cut through it gently where the chain stays are, just as that is where the minimum amount of thread is to get damaged. then take to it with a chisel, pushing the cup inwards. this should fold it in and make it smaller than the BB shell. should just be a matter of tapping it around the edges and it should fall out.

    your dad would probably have an answer and tools if he deals with old Citroens anyways

    or clamp it in a vice or melt it out.

    getting heat on it anyway will def help get it out.

    failing that cut through further and fold it out. you have a lot to work with

    i would cut a slot and try to undo it like a flat head screw, maybe put a thin bar in a vice and turn the frame by hand.

    just as a point of reference in case it crops up in the future, these freewheels dont have the collar ring so you cant remove them the destructive way, that and the lack of tool makes them an utter bastard to get off.

    theres a shop in Brighton called freedom bikes who have the tool and will get it off while you wait for £5, should you be in that part of the world

    ive found for front brakes its pretty irrelevant since the distance between calipers and levers are so small. ive used cheap ass stuff for front brakes and its worked perfectly for ages.

    rear brakes its more of a concern - outer cable makes the most difference imo

    since its your first bike of this type, if i were you i would just get some budget secondhand 700c wheels, take the cassette off and put a 16t freewheel on in its place.

    just get a 3/32 16t freewheel off ebay theyre under £10.

    then just redish the wheel, take the gears off completely and cut the chain down.

    only a SS set up but its a good start and gets you going quickly for cheaps
