Identifying marks

[Georg]

hello

these two pieces have different marks. Saucer is marked with the mark attached
Cup is hallmarked with a RD number under 170000, inside a blue rectangle, Below the rectangle with the number, the letters H & A C. Do you have any guess regarding age and manufacturers?

Pieces are very similar in colour but designs seem not to be the same.

Do you think they are somewhat interesting pieces? Thanks

[Georg]

I meant that the RD number is smaller than the cypher 170000

[Georg]

apologies fo mistake:

marks are HA & C

[Georg]

Are these marks, then, unknown?

Whatīs your opinion on these pieces(possible interest)?

Regards

Looks to be two different pieces !!  Is the pattern name "bouquet"  the same on both ??  Difference in color can vary depending on the year made !!  Sometimes an old pattern is made years apart !!  I am assuming this is English pottery ??  Possibly makers ,,H. Alcock & Co,,H Adams & Co,,H.Aynsley & Co.  !!

Hello

buquet is only on saucerīs back-

[Georg]

I have been trying to find information on this pieces, but my finding was unsuccessful.

Then only can ask your opinion, about its visual interest, being , as mart says, two slighty different pieces.
Also, do you think could be victorian or, rather 20th?

[mart]

You can check replacements.com for that pattern name and see if they have the year made and the colors it was made in !!  Their prices are a bit high but it should give you an idea of value per piece !!

The english registration mark of 170000 gives you the date code of 1891.
