Blazon: Azure a hazelnut between two branches issuant from a demi-wheel of twelve spokes in base or
The municipal arms are apparently a combination of elements from three noble houses that were prominent in the region. The hazelnut is apparently from the Ellerbachs (the depiction provided looks more like an acorn to me, but more on that in a minute), the demi-wheel is from the Erdödys, presumably related to the Hungarian-Croatian Erdődys, and the branches are presumably from the arms of Bernhard, although I cannot find a corroborating depiction. The acorn may have been changed to a hazelnut for canting reasons; the town was initially named Monyorokerek, which means, roughly, “hazel circle” in Hungarian.
Blazon: Argent a broken eight-spoked toothed wheel sable
The wheel is the symbol of St. Catherine of Alexandria, to whom the local church is devoted. She was condemned to die by being broken on the wheel, but legend has it that the wheel shattered at her touch.
Blazon: Per fess argent and azure a six-spoked wheel counterchanged
In some seals from around 1790, the town is shown using the Sester as a charge. However, the wheel was formally chosen in 1895 as an allusion to the arms of the Lords of Eschingen. The tinctures were drawn from the Fürstenberg arms.
Blazon: Sable in the dexter chief a six-spoked wheel and in the sinister chief a horse salient, pointé in base argent a lion rampant gules
The wheel in the arms is probably drawn from those of Michelbach an der Lücke, a former municipality incorporated into the town in 1974. Hengstfeld, incorporated the same year, bore the arms argent a horse salient sable on a base vert; the horse may be a counterchanged reference to this town.
Blazon: Per fess argent a wood grouse proper and vert a demi-wheel of five spokes, two broken, issuant from the base of the first
The broken wheel may be a reference to St. Catherine, patroness of the local church. Unfortunately, the wood grouse has no discernible source. (And I am deeply horrified by the poorly photoshopped charge in this depiction. I cannot imagine what a town must have done to deserve that.)
Blazon: Lozengy argent and sable, on a chief or an annulet of the second between two torteaux
Crest: On a wreath or and gules in front of a wheel issuant therefrom a mount sable lozengy argent rising therefrom in its flames a phoenix proper
Mantling: Gules lined or
Motto: We seek the best
The annulet is derived from the Plumtree arms, and the torteaux from the Greys of Codnor. The black diamonds and the flames in the crest are intended to symbolize coal mining and the energy derived from it. The wheel is a reference to the town’s history with the Midland Counties Railway, which was initiated in Eastwood in 1832.
