25-pr. M.L.R. Gun-Carriage and Limber, Mark I. 
This carriage is similar in construction to the 16-pr. gun-carriage 
Mark II. ;* having the same wheels, but with an additional bearing- 
piece riveted round each trunnion-hole. 
The elevating gear is of the worm-wheel pattern, similar to that of 
iron siege carriages; the worm wheel being made composite, to allow of 
some slip on firing, and so reduce the shock upon the parts. The 
carriage is also fitted (like siege gun-carriages) with a wooden stool- 
bed, large quoin, hand quoin, and scotch, which can be used for laying 
the gun in case of the worm-wheel gear being damaged. 
The other fittings of the carriage are the same as for the 16-pr.— 
viz., for axle-boxes, drag shoe, wadhook worm, &c. The axle-boxes are 
similar to those for the 16-pr. carriage, but without guard-irons and 
steps, and only fitted to carry small stores. 
The limber is the field limber, Mark II.,* the “ off ” and “ near ” 
boxes carrying each 9 rounds: the projectiles steadied by cleats and 
fitted with lifting straps.

as well as the 40-pr. M.L.R. of 34 or 35 cwt., is made much stronger 
than Mark I. carriage,! which only takes the 34-cwt. gun, and from
