record cl2 help

G'day all looking at getting some advice for my lathe its the blue record cl 2 ,my question is I would like to change the pulleys from three speed to 5 speed by changing the pulleys is this possible and if so can someone advise me as to where I might be able to get them I wish I had the funds to make it variable speed via the electrics but that aint gonna happen just yet so thought the pulleys will have to do for now .

any info would be great cheers osage..
