Please can you help identify?

could be artillery shell buckets. but wait for spring, he might know more.
what's the measures ?

 

Any chance of a good close up of the coat of arms ?

 

Hope this helps.

 

Material, size, do they open, pictures of top and underside, and any provenance all help.

 

the bigger ones were indeed used as sand buckets when the war was over

 

You'd think the shells were heavy enough to begin with !!
