The attached shows a No.13 light pitcher, body made of steel. The No.14 heavy pitcher used cast iron.
They are not commonly found. Ground dug Battyes seem to turn up far more than these pitchers. Probably only 40-60,000 pitcher Nos 13 and 14 made their way to France and Flanders.
Contract records identify the first 20,000 light and heavy pitchers made in April-May 1915. Figures for June are absent but records show 218,325 manufactured from 1 July to 9 October 1915, giving a production total for both light and heavy of around 240,000 plus the June batch.
Owing to the dangerous nature of the grenade, it was quickly discarded and many were left unfilled. A Trench Warfare Supplies report for week ending 5 February 1916 identifies 63,000 awaiting filling at the Filling Station and 140,000 at Woolwich, a total of 203,000 destined not to be used - even the Russians didn't want them.
A salvage report of February 1918 identifies 72,019 pitchers having been returned to the Bristol grenade and bomb salvage depot to be scrapped. Other batches were broken down elsewhere or dumped.
