since the chainset is likely RonKit sourced would expect Brit dimension cotters of 9.5mm and Brit dimension pedal threads
three components was unable to ID from images provided were pedals, brake calipers and headset
locknut of headset looks like it might be TDC, also a TDC headset would be consistent with a TDC bottom bracket assembly (wild speculation)
perhaps one of our framebuilder members will recognise the cycle's ends set
please post updates as you work with this new arrival, its most enjoyable to see
