Unfortunately, the answer I have for you is quite obtuse. Without seeing VERY good quality photographs, or actually seeing the reel in question, it's impossible to put anything like an accurate value on the real. Even after examination, a valuation would be, at best, an 'educated guesstimate'. In real life, the reel is worth either a/ what someone else is prepared to pay for it b/ the price you would need to pay to replace it (which may well depend upon exactly how badly you want to replace it!) Both of these are affected most of all by the condition of the reel itself, and value is usually enhanced, often disproportionately, if the original box, case, spares, documents etc are present. A while ago, I sold a similar reel via EBAY (sort of) for a price well in excess of anything I expected. A little searching on there for reels of the same type (amongst the completed listings) showed me the prices the reels had been selling for. It was apparent to me that mine was far superior, and I had noticed that a (Japanese) buyer was bidding frquently on such reels.
I contacted him with details, he asked for a price for me to sell at. Quandry ... as I still had no real idea. So ... I put on a price that I thought I'd be happy with, then added a further 25% (figuring that he would probably try to negotiate). Still not sure why, but at the last moment, before sending the email, I doubled the price ... and he still said YES without hesitation!. Could I have got more? Possibly. Was I happy to still sell at that price? At more than twice the highest I had in mind? Take a guess:-)
