<p>Oh...I did not get it at first, sorry. It was GDR's ORWO Chrome slide film most likely day light UT-18. It used to have green/red strip and red half usually was removed upon reload. The original spool had quite inconvenient latch so it usually was replaced with less polished but more robust Russian counterpart. http://commons.wikimedia.org/wiki/File:%D0%9A%D0%B0%D1%81%D1%81%D0%B5%D1%82%D0%B0_ORWO_CHROM_UT-18_%D0%93%D0%94%D0%A0,_1983_%D0%B3%D0%BE%D0%B4.jpg</p>
