May 20, 2017 at 5:20 comment added AndreJ The zone number in +proj=utm surely works only for integer values, representing 6-degree-wide zones. But there have been 3-degree-wide transverse mercator projections in the past, like the German and Russian Gauss-Krueger system.
May 19, 2017 at 23:38 comment added Steven Kay can you edit your question to include (a) your .prj file (if it's a shapefile) or the output from gdalinfo if it's a raster, (b) the area you're looking at and (c) how old is the map. I found a possible match on spatialreference.org but not sure unless you can post more info.
May 19, 2017 at 22:37 comment added mkennedy I'm afraid I don't understand what you're getting at. To me, 32.5 means that the central meridian is halfway between 32's and 33's, thus, 12E with all other parameters remaining the same. I could be wrong though!
May 19, 2017 at 22:33 comment added Daniel Pardo @mkennedy I know how to create a custom UTM zone with integers, but I dont know if have any sense a zone and a half
