One of two kits received at Christmas the AZ Model He 162 B-6 actually has parts in the box for a B-1 through to the B-6, see photo of variants, and also has the fuselage parts for the 162 S trainer/fighter. This means I can build the latter needing to find/make just the fixed undercarriage for the unpowered trainer and more difficultly the long canopy.
The kit consists of 72 grey plastic parts and two clear with a four page instruction booklet, a decal sheet which includes seatbelts, the camoflague options being on the reverse of the box but as this is a Luft 46 'What If' we'll see what I decide to do at that time.
Now for the conundrum. The variants shown on the booklet give a B-6 as a single Argus As 014 where it should be double, plus the single Argus' should be the As 044 which has a bigger diameter body. Further to this a Polish Profile I have, No. 49 The Heinkel He 162 'Volksjager', calls both single and double versions the A-11. William Green's 'Warplanes of the Third Reich' just calls both single and twin Argus' 'B's and it also shows both the 'C' variant with a BMW engine and swept back wings and the 'D' variant with the forward swept wings. If you want a cupboard full of 'Salamanders' then AZ Model make kits of all the above mentioned, and then some, excluding the S unpowered trainer.
