John and George, indeed one is spoilt for choice when entering the 109-world.
@johnb, even if you stayed with the "Emil" the variations are countless.
@gblair, one source that seem very trustworthy is the book on 109's in Spain (German eagles in Spanish Skies by David Johnston) - actually I have bought a lot of original and instructions from Luftfahrt-Archiv Hafner in Germany. He has scanned a huge amount of manuals and POH and what-not. I better stop here, with the note that I do recall your Emil - it was a very well researched build, and definitely worth a re-visit!
