Steve,
The other small hand grenade (bomb) were ones manufactured in Malta, from memory a round cast iron and brass bomb with lit fuse. A search of this site for Grenades should bring up either a description and/or photograph.
The Lotbiniere bomb was developed by Major-General The Hon. A. C. de L. Loly de Lotbiniere, C.B., C.S.I., C.I.E. R.E. Chief Engineer on Birdwoods staff. At landing on the 25th April Engineer officer in charge, 3rd Brigade. (Official History A.I.F. Vol 1, pages 209, 280, 457 & 573.
3rd Aust Inf Bde war diary, April 1915. (AWM War Diaries)
Tuesday 29 June 1915, 8th L.H. Regt, Russell's Top.
Sgt Major Worrall recorded in his diary: “Our men are very weary but wonderfully cheerful. We tried a
new style of bomb called the ‘Butterpat’. It consists of a two and a half lbs of gun cotton and a two
seconds fuse wired onto a piece of board with a handle like a butter pat. These were discharged from
No. 2 Sap, which is only 15 yards from the enemy’s trench. The result was more than we expected.
Earth was thrown from the Turk’s trench back into our firing line, 40 yards away, the earth shook as
from an earthquake tremor.”

The stick bomb I have no idea, other than it may have been the bomb fired from the Japanese mortar, that had a wooden tail-end that fitted into the barrel of the gun.
Or is Bean referring to the Lotbiniere bomb?
