Here is my 1/40-somethingish scale MT-LB, seen here with a T-55 to raise the tone somewhat. And it's not often a T-55 has that effect. And yes, my model is too wide but it does have a vague look of MT-LB to it.
The lower hull MT-LB started off as a block of insulation foam which was then carved roughly to shape.
The upper hull and hatches are made from balsa and the turret came from the spares box.
