Hi. I have just found your site. I was in Spain around the mid 70s, and the Spanish sections RENFE STEAM 1972 and RENFE 1973 bring back memories. Unfortunately my photos were not good, and in this day and age they look terrible. I note you say to contact you, so I was wondering if I could acquire all the photos in these two files? They would be for my own personal use only, not for any commercial purposes.
I don't know how your site works so if you charge for the photos, it would be too expensive for me. I did have some luck on another site, french. the site owner sent me 50 photos, as long as i could assure him they for personal use only. Hopefully you are of the same mind!
