Compare 1 source-linked mark variant recorded under William Dunningham & Co. These are reconstructions for comparison, not source photographs or authentication evidence.
The initial sequence, the two joining symbols, and the enclosing rounded rectangle are retained in the observed order; the enclosed counter remains attached to its glyph.
Prices remain in their original currencies; buyer-premium inclusion is unknown. These are reviewed maker-name auction examples, not proof of an object's attribution.
This maker-level evidence does not value your object. Matching a mark cannot establish authenticity, material, condition or provenance.
Maker labels and date or location statements follow the cited source records. Similar names across source collections have not been merged. Compare the photographed mark and the complete object before relying on a resemblance.
