Javier,
I wish them all the best in the reconstruction. What a project!

Model 75s are pretty rare. I've never seen one in the flesh, only in 
catalogues. Probably because the British Post Office never adopted it. 
Never seen the Model 25 perforator either, though I did own a Model 7P 
re-perforator at one time. The later Creed model, the 444, had an 
integral punch makng the separate perforator redundant.

That may be the way to go. A Siemens T100 would be a great interface for 
kids to get their hands on. And probably more reliable than the Creed 
anyway! The models I've seen had an integral tape punch and reader.

Cheers,
