For those of us who model aircraft in the one true scale of 1/144, it is no secret that some details, particularly when it comes to cockpits, can be nonexistent at this scale. Most are often just a space with the occasional seat and maybe a control column included with the kit. Often that cockpit area isn't even there and is 'blank over' by the manufacturer. Just part and parcel for this scale.
Brengun has and continues to produce some lovely small-scale(144th) aircraft kits. They have also been in the habit of producing some after-market photo-etched/resin detail kits to address the lack of detail in those kits. Such is the case with the model accessories set (#144167) for their Me-309 aircraft kit(s).
The model kits are the Me-309V1/V4 (#144015) and the Me-309V4 (#144014), both in resin. These are neat, well-molded kits for an aircraft that has been largely overlooked by other mainstream manufacturers.
