Your recollection is spot on for hulls >= 100 d-tons.

Here are the rules for small craft:

1. CT LBB 2 Starships 1977 6th printing pages 17-18: "Weaponry may be added to small craft. Each small craft may allocate one ton to weaponry and install up to three weapons. The individual listings indicate specific weapons which are available."

In LBB 2 you purchase the turrets separately from the weapons which, in my opinion, allows one turret with weapons installed or fixed mounted weapons.

2. CT LBB 5 HG2 1980 12th printing page 34: "Weapons: A small craft may mount the equivalent of one turret. In actuality, the mountings are probably rigid, and no actual turret is present. All computations, however, may assume that the craft carries one turret. Weight, tech level, cost, and energy point restrictions must be observed."

CT: Alien Module 6: Solomani has rules for fix or rigidly mounting weapons.

3. MT Referee's Manual 1987 2nd printing

Page 57: "Craft: Any transportation unit is a craft. Craft may be any size. Types of craft include vehicles, small craft, spaceships, starships, aircraft, and watercraft."

Page 59: "Hard Point: A hard point is a necessary measurement of hull pre-allocation to allow the mounting of very large weapons without affecting the structural integrity of the hull. Of the four weapon categories, only a gun mount does not require any hard points."

Page 63: "12 Vehicle Cupola?
     Determine if the vehicle has a cupola or turret.
     A cupola is a fixed extension of the hull. A turret is a movable extension of the hull.
     Select the desired size of the extension (5 percent to 40 percent of the hull volume).
     Increase hull volume, weight, and price by the selected percentage.
     A turret uses 0.01 megawatts of power (for movement) per kiloliter of turret volume.
     More than one turret or cupola is possible as long as the combined total increase in hull volume is not more than 40 percent.
     Because a turret or cupola is typically such a large part of a vehicle, it is determined at the same time as the hull. Starships and spacecraft (on the other hand) determine turret design along with weaponry.
     If you plan to mount a weapon on the vehicle, you should have some idea of the weapon volume needed-you might look ahead to the weapons design section and pick out a weapon at this time. Then return here and design the cupola or turret."

Page 71: "A hardpoint is an installation point for a weapon. Large weapons may require more than one; hardpoints may have either fixed mounts or movable mounts installed. Divide kiloliter volume of the craft by 1350 for the number of hardpoints it can have. A craft always has a minimum of one hardpoint."

Looking at the above sources and the write-ups my conclusion is that in MT all craft can mount one turret if they have enough volume space and can meet the power requirements.
