concours judge taking note of dynamo absence

would think the two most likely national origins would be DE & NL
barrel of rear hub should exhibit markings such as Torpedo, F&S, Komet, etc.
these markings may include a date, either in the open or in coded form
threading of steerer and bottom bracket shell will be BSC
wheel rims should be marked with both size and brand
possible pedals may show marking on endcap or barrel, the two most likely candidates are WECO (Wertheim) and Union Frondenberg
chain stay bridge appears to be ESGE Pletscher
levers which operate hinge and seat binder sometimes exhibit a name or logo
provision of attachment point for mudguard mascot suggests more DE than NL... or one might argue it represents an attachment point for a lamp
is there a brand name on the brake caliper?
placement and format of serial can sometimes be a helpful clue
suspect stem/bar may not be original; usually on these there is a manner of quick release to be used at time of folding/unfolding
a "ghost image" from the machine's headplate remains on head tube; if you could post an image of it it might twig a memory for a reader...
