Murray, the Indian type harmoniums look like wooden boxes with a keyboard. They can be placed on a stand tall enough for the player to stand and play, (as the chorus director did during the funeral of Mother Theresa) or placed on a table so that the player can sit on a chair, or placed on the floor, and the player sits on the floor to play. As far as stops etc., there are different types from simple to deluxe (and prices). I copied descriptions from a couple of manufacturers:

Harmoniums

First brought to India by European missionaries, the harmonium has, over the years, been adapted for use with Indian music. These days almost any occasion which involves singing, be it classical, devotional or folk, solo or group, concert or teaching, includes a harmonium as an accompanying instrument.

Harmoniums come in a great variety of styles. A harmonium can be characterized by the number reeds per note, by the quality of the bellows, and by the number of drones and stops it has. Deluxe options include a scale-changer (the keyboard can shift up or down one to five notes, thus allowing easy transposition)and an octave coupler (doubles the octave).

Simple or fancy, a harmonium should come from a good maker - one who will use good wood and take proper care. We usually have harmoniums from Pakrashi and Dwarkin, several of the best and oldest makers in Calcutta.

Harmoniums

The harmonium is an Indian musical instrument, somewhat akin to the early American pump organ. The piano-like keyboard is played with the right hand, while pumping the bellows with the left. Harmoniums give an amazing amount of good sound and music, even for the beginner with little skill or experience. Their mellow, warm-sounding tone blends well with the human voice; thus they are especially well-suited for individual or group singing. The handcrafted harmonium makes an attractive addition to any home. The convenient size about (1 ft. x 1 ft. x 2 ft.) makes it easy to move about or store, and still have at your fingertips when you want it there. The harmonium requires little maintenance and servicing, and is reasonably priced. Each is its own individual instrument with a unique sound and style, differing in volume, tonation and performance characteristics.
