I'd go with stag
Cooke: Argent, a bend azure, in chief an annulet gules. Crest: a stag trippant argent.
Foster: A cheveron between three bugle-horns. Crest: a stag passant.
Think my money would be on Cook(e)
Thank you.
Just read in Fairbairns that an antelope has the body of a stag and an antelope is of the deer kind, so a hind is close too.
Because the stamp has been applied at an angle twice revealing only the lower half of the body and the seal inside the Will defaced by being flattened, George has got us again!
A check would also be required to see if there are any headless animals of that kind, but on the Will outer seal (edges broken away) the wax has not formed the top of the body, due to pressure on the stamp being at an angle.
On the cord there should be six alternate twists and we see six ovals.
If a genuine seal of a crest, I am very much reliant on finding a written record, it does not need to have passed from a previous generation either, but can be left in a Will, or granted and even belonging to another family name.
For example Henry Mitton of Snaith, took the Arms of Eadon ...

If he didn't we could be really stuck.
The two seals appear to belong to the same stamp, so we can rule out it being a bird in the seal of George Hood next to his signature.
Seems the example you found Claire is possibly for Cooke of Cambridge? Those crests were found in Cambridge.
Kind regards Mark
I have an apology to make, I am sorry as it seems Philip Holmes did not take over Richard Gibson's business, as the tax value does not correspond.
