Auxiliary Cavalry 'A'

• The skulls are hemispherical with recesses for the ears and with deep extensions at the occiput terminating in rather small neck flanges of about the same proportion as those on cavalry sports helmets.

Auxiliary Cavalry 'B'

• Similar to the previous type, but with a more sloped and slightly broader neck guard.
• The upper part of the skull is of iron, with a bronze casing. 
• There are large bronze bosses attached to the neck guard, to the occiput area and just above the ear protectors. There is additional decoration to the casing in the form of punched raised lines.

Auxiliary Cavalry 'C'

• Made from one bronze plate.
• From the apex of the hemispherical skull, a short point of triangular outline has been raised.
• The back is deep and terminates in a small, slightly sloping, neck flange. 
• An embossed rim crosses the brow and runs into the rather shallow ear guards, made in one with the rest. Above these, and following their outline, is an embossed rib.

Auxiliary Cavalry 'D'

• Has a well formed hemispherical skull with a very deep back that brings the broad neck guard almost to the shoulders.
• There are applied bronze ear guards with broad flanges and the brow plate is brought to a central point on the lower rim.
• A low crest runs from just forward of the centre of the crown to a short distance above the neck flange where it is secured by a large cone-headed rivet at each end.
• The neck guard is bound at the edge with a bronze rim. 
• The cheek pieces were extremely large and enveloping and with very wide throat flanges.

Auxiliary Cavalry 'E'

• Very similar to the previous type, but with in addition a transverse reinforce for the skull.

Auxiliary Cavalry 'F'

• Very similar to the previous two types, but with no applied decoration.
• The ear guards and border across the brow were raised out of the skull piece.
• Ball-headed rivets were used to secure the peak and reinforces, instead of the cone-shaped ones. 
• The edges of the neck guard have been notched to retain the edge binding.

Auxiliary Cavalry 'G'

• Has a transversally ridged brow plate embossed with projecting laurel and oak leaves and also a central human bust. 
• The neck guard was quite wide, compared to the other types.

Auxiliary Cavalry 'H'

• Made of iron with applied bronze sheet decoration. This last is engraved with feather-like scaling and writhing serpents.
• In the centre of the crown is an anther - a hollow bronze knob rising from a convex square base. This represents a poppy seed case.
• The brow band has a pointed peak on the lower rim. 
• The neck guard is wide, and considerably dished (similar to the Infantry Imperial-Italic Type-H).

Auxiliary Cavalry 'I'

• A plain, deep helmet with a large neck guard of the same shape as the previous type.
• The ear pieces are very large and the rounded shallow ear guards are worked out from the edges. 
• An upturned pointed peak is attached to the rim above the brow.
