2 canisters, maker unknown: Orzel (or Royal Oak)?

Two slipcast canisters needing corks

Left is 120 x 75 x 98
Right is 158 x 90 x 110
Both have flat bottoms

Shown with the Orzel canister I just posted at:

And then again, maybe they are Royal Oak.

The brown glaze is a good match for the Orzel lidded canisters

but the shape is a good match for these (below, two different sizes)
which, despite masquerading as Orzel with those cheeky drips, I know to be Royal Oak because this one (left below) has glaze to match the Royal Oak mug (right).

All together now...

Jeremy has raised a tricky issue here, and I am adding this note so hopefully I will remember to come back to it.   There is very little difference between Orzel and Royal Oak kitchen cannisters/spice jars.  It is possible to differentiate when the glazes are specific to one manufacturer, or when the Royal Oak ware has the distinctive 'smear' of glaze on the base.  However - some glazes, especially the mid-browns, are very similar in both Royal Oak and Orzel.
The two pale cannisters with dark brown tops (under ' Second thoughts") are definitely Royal Oak. The others are probably Orzel but I can't guarantee that.
