I did a google search for these, and discovered a pair sold on ebay about 5 years ago; one shoe numbered 3/25 & the other 11/25. When I asked the seller, he said that it was him, he had bought 2 pairs because he wanted to het both shoes numbered 1/25. He sold the 'leftover' 2 5 years ago and kept the 1/25 set. However, now he is selling them too as he needs the money.
