Red Glaze Vase Made in England - Moorcroft

Does someone recognize these maker marks? I am unable to decipher the mark on this vase. It is stamped Made in England and has another mark and a name. Thank you.

The "Signature" is a slightly incomplete "Moorcroft" (shown upside-down).

Thank you! Much appreciated.

I think the other mark says POTTER TO H.M. ......... (would be a Royal Warrant),
but is not really readable.

Did Moorcroft number their items? There is a hand engraved number on this also. I'll get a photo.

This is the hand marked number

Yes, it could be a shape or pattern/glaze code.
It could be earlier Macintyre, where the Moorcroft signature was also used, but I
don't have much information.

Thank you again.
