hi, we have had this blue mantel winding clock and vase set in our recent family for 40 years passed down from older family who we think had it for maybe 30 years and its just been a complete mystery to us of who made it and its value and i've come here hoping somebody might be able to help us find out

the clock doesn't work anymore and i think it used to have a cover on the clock face.
here are some pictures, there are stamps on the bottoms but they are very faded and i couldn't make anything out on them but am hoping the numbers might mean something to somebody, you can click the pictures for bigger pictures.
the set

the clock face

the numbers 856.6 on the vases

the numbers 856.11 on the clock

Thankyou so very much to anyone who can help
