Changing a calculator ribbon

Time to change another ribbon, however this time not on a typewriter. The ribbon being changed is on my big mains powered Silver-Reed 1250PD calculator which has a built-in printer. This was a fairly easy job, the ribbon and it's spools being very similar to the type used on typewriters, though a bit smaller. The calculator now produces clean and crisp results in both black and red (for negative values) - the latter will be more handy if i do my finances on it!
