Looking for: Messerschmitt Bf 109 E-3 1/48

Personally, I would look at the Eduard kits.  Keep in mind that your picture shows the later canopy.  Some E-3 kits will have the earlier canopy.  I'm not sure about some of the markings, however.

I gather your new to modeling, so I would go with Tamiya's E-3.  Its a gem and more user friendly than the Eduard kit.  For paint, you will need RLM 02, 71 over 65 which can be found in the Model Master line at any hobby shop.  I believe they have acrylic (water based) and enamel paint (oil based) available.  They have the yellow (RLM 02) a well.  Aeromaster makes decals similar to your subject above for Battle of Britain Emils, perhaps even "White 14".  Ebay has a great selection.

Good luck,

Joe

Airfix I believe has this model pluss the decal with x in the circle. It looks the making that yoused used in Spain. If your more interested let me know and I'll dig out the stash and give you the kit #

I withdraw my Eduard suggestion and second the Tamiya.  The Eduard weekend kit is a bit cheaper, but it is also more complex putting the nose together.

I'd go with the Tamiya kit, Eduard kits have softer plastic which can make them trickier to build.  As for the painting I'd recommend using the Mr. Color line if you can find it.  They're more accurate than the MM RLM  shades IMO.
