AB-204B Bristows 'VR-BDX'

VR-BDX was based in Muscat and Khasab (Oman) around 1980, assisting with the installation of electrical pylons. I'll be using the italeri 1/72 UH-1B and CMK detail sets for the interior and for external details. My initial choice of kit was the italeri 1/72 AB204 (makes sense of course as VR-BDX is/was an AB204B). However, VR-BDX was not fitted with a Gnome engine, as per the italeri 204 kit, which is fine as I was going to use the CMK kit which as far as I know represents a Lycoming T-53 engine. Also, and this is where I'm confused, but the tail boom of VR-BDX looks to be the same length as a UH-1B. I was under the impression that civilian AB204B's were all built with the extended tail boom and larger diameter main rotor?Using a very rudimentary comparison involving a picture on my ipad and the two fuselage pieces, one from a 1/72 UH-1B & the other from the AB204B kit, it would appear that the UH-1B kit is the correct length for VR-BDX.
