There is a super long thread on these  bins here https://www.cloudynights.com/topic/536652-home-built-nikon-2x54-widefield-binos/page-29?hl=%2B25+%2B54#entry7832800 . I purchased the Nikon TC-E2Tele Converters as new items from 2 different Ebay sellers for less than a total sum of £40 back in early 2017. My youngest son acquired a 3D Printer back in March so printed the housings for me. from information in the thread. The Nikon lenses were in excess of £100 each when first marketed but fashion moved on to DSLRs so prices  fell right down.
