stirrup ?

[garrelt]

I was reading/looking through the Curle 1911 Newstead documents (pdf) and in chapter XIII

Tools and Implements

, page 31, i came across the picture attached.
The links for these documents/chapters you can find on this forum.
The numbers 6 and 14 caught my eye.
Number 6 looks very much like an "Avar" stirrup and number 14 has the same features as a late medieval/modern stirrup.

In the text on page 30 number 6 is described as

Ring with two loops, probably part of the mounting of a small pail.

and number 14 as

Manacle (?)

.
The original page for these objects is 288.

So my question is:
Being an old excavation report has there been a new dating of these finds.
If the dating is correct then this could help the discussion about the use of stirrups in Roman time.
Looking forward to your answers.
