I have a very old cast iron 3foot guillotine, my husband used it to cut small sheets of stainless steel. It has a foot peddle to operate the spring to raise and lower the blade. I cannot locate on the guillotine a makers brand or model number and somebody suggested that it may be made by your company many years ago. I can send photos and measurements if you would like to view the machine
If it was made by John Heine, it should have our name cast on the cutting beam or on the legs. You can send a photo to us - firstname.lastname@example.org - and we will see if we recognise it.
