Originally, the first ten machines ordered by the RLM for trials were to be referred to as 'A' series, but this was changed in the nomenclature to B-0, and this perhaps includes all of the Jumo powered aircraft produced after the Kestrel powered V-1 prototype, including aircraft referred to as V-2, V-3 etc., up until the the B-1 series was officially started. However, other sources state that there were 3 'A' series machines: V-1 (D-IABI), V-2 (D-IILU) and V-3 (D-IOQY). Still other sources state that the B-0 series did not start till after V-7, and that V-4 through V-6 are more correctly seen as prototypes for the B series.

One thing that is clear is that V-1 through V-3 had different cowls than are represented in the kit being reviewed. Also, V-1 - V-3 had unbraced canopies. The canopy provided with the kit is the normal braced type canopy seen on all 109s after V-3. Thus the kit cannot be said to represent the 'A' series at all, but rather the B-0 series and its prototypes.

V-4 clearly has a prop of the type that is supplied in the kit in resin. It also had an engine-mounted MG, so it is necessary to drill a hole in the tip of it to represent this.

Supposedly only V-4 (D-IALY), V-5 (D-IEKS), and V-6 (D-IHHB) were lacking the extra cooling vents in the cowl that is represented by one of the cowls in the kit (markings for both provided in the kit). However, one can find many pictures of 109s in Spanish and German service that lack the three vents at in the top fore portion of the cowl and the ones on the side. So, if only these 3 machines lacked the additional vents, they must have seen a lot of service while dressed in many different markings.

V-7 (D-IJHA) does not appear to have any weaponry, though it does sport the cropped cowl and variable pitch prop seen on B-2 series and later machines. It also has an extra chin scoop nested inside the radiator intake. It is covered with a monotone gloss paint (RLM 63?) and it sports a “4” on a white square, evidently for entry in an air race.

As far as I can tell, the kit allows the modeler to reproduce and machine from V-4 through B-2 machines. References claim that only 3 machines are valid to use the cowl that does not have the additional vents, though I am somewhat dubious of this. Studying the photos I can find, it is difficult to tell if the machines called out in the instructions as being overall silver or aluminum are actually these colors or rather painted gray. Photographic evidence proves the Spanish civil war machines that markings are given for in the kit (6-3 and 6-10) did not have the additional cowl vents. In fact, the lowest numbered aircraft I can find proof of clearly having these vents is 6-15. Clearly 6-4 and 6-7 are without, and perhaps 6-16 as well (note these numbers were recycled on later machines as well once the originally deployed 109s were destroyed or withdrawn - and aircraft were also refitted with parts from the later series as well). All of these aircraft have the style of spinner given in resin in the kit, and seem to not have any hole for an engine mounted MG in the tip of it despite records claiming that all these aircraft should have this gun mounted. There is evidence in some photos that the hole might have been there but was plugged
