I've had this for about a year. The former owner said he thought it's German (possibly former DDR). Looks 1950s era to me, but hard to say. Only identifier is the brand 'Elite'. I can post more pics if anyone thinks they could ID it.
I can find no information about this marque, other than that there was a former East German bicycle concern called Elite-Diamant-Werke AG. However, all their bikes were branded 'Diamant' and I can find no evidence that they branded any 'Elite'.
Any insight appreciated.
Here are a couple more photos:
The bottom bracket has a grease nipple, a practice which I believe ended in the early 1960s. The bearing itself is marked 'BSA' (Birmingham Small Arms), but is possibly not original.
