Nice looking machine. It is nice to have all the 'goodies' with a machine.
I don't have this machine but do have a White that is similar. It will take 15x1 needles. The hand wheel turns the opposite direction from what you are probably used to. In other words the hand wheel turns clockwise as you are looking at it from that end. The tension is a little fiddly to get threaded correctly. The bobbin threading also takes some practice to get used to.
There is a thread about this machine at
Domestic Rotary 153 Somewhere in there is a QB link for threading the bobbin.
Because these machines are friction drive rather than having a belt, they frequently have a flat spot on the pulley from having set on the hand wheel for so many years. There are a lot of threads about that. My suggestion is to place something between the motor and the machine. There are a lot of suggestions as to what to use, such as wooden clothespin, wooden spoon, even a piece of folded fabric. You just want to keep the pulley from resting on the hand wheel when the machine is not in use.
