Hi,
The Vietnam turret basket.
Sheridans arrived in Vietnam with their small storage basket at the back of the turret, not big enough for Vietnam. With the equally limited space inside the vehicle, the crew and units customized their vehicle to their difficult environment.
Although I can see many variations of custom baskets in reference pictures, vehicles of the 11th ACR (Blackhorse Armored Cavalry Regiment) obviously developed some standard field modifications, shield, gunner's machine gun, and the storage basket. Its not easy to figure out the shape of the basket because they are always shown filled to the rim or somewhat damaged. The Sheridan turret is asymmetrically round with sloped armor and many different angles. A few 1/35 PE detail companies have produced their vision of the Vietnam basket, but none look the same, they all made assumptions and some are better than others. They can be used for inspiration but the 1/16 modeller must be careful as these 1/35 basket kits can lead to bad mistakes.
In the 1980s, the army equipped its Sheridan with a new standard basket, larger and solid. However, the modeller should not use this basket model for a Vietnam era vehicle.
The main issue is that the Sheridan turret is not really round, its asymmetrical, and so is the basket. The Tamiya turret opens horizontally in 2 halves right in the middle, and the basket has touch points on both upper and lower turret, complicating things and forcing some compromises. Also, there is not a single flat surface of the turret sides, complicating things when you are building the basket out of nothing and the builder need to define some orientation and anchor points. After a lot of study, I started the basket with a "best effort" mindset, as if I was a mechanic with a blowtorch in a field unit and tasked to create a large basket for the unit tanks. None will be exactly the same. Before cutting specious grill material, I would recommend the creation of a template in order to determine a shape that seems to fit key critical points, such as the basket starting points on both sides, height of the support in the back, height of the basket itself, but most importantly the locations of the basket corners and supports. None are obvious but its important that it looks right. Study of 1/35 PE basket kits on the market led to more confusion than help. One that look about right is from FC-Model Trend. Here, the first 3 supports are glued to the back bottom after a tentative shape is created.
The grill is cut and positioned. Many angles, its difficult to determine proper position (up, down, left, right) and its easy to make mistakes. It looks close but its not perfect, and I am running out of grill material...
The builder need to keep in mind that the turret halves must remain free to open to access the electronics inside. Can't glue basket to points on upper and lower sides unless you are building a static version. Therefore, the basket is not exactly how it should be, but close enough.
The finished turret basket.
Despite the optical illusion due to the shapes and angles, the top of the basket was kept perfectly lined up with the top of the turret, the only constant.
