Brass Bolt by Rocky Chiaro (I think..)

I think this is 'Brass Bolt', which is the Bits & Pieces version of Rocky Chiaro's Ring-N-Nut puzzle. 

I have included a photo from Rocky Chairo's book, showing what looks like the puzzle on this listing, so I am 'reasonably' confident that my identification is correct, although I am not certain beyond any doubt, so please bear this in mind when bidding. 

The puzzle appears to be in excellent condition, although it might benefit from a polish as there is some surface tarnishing. 

Having had a brief play around with it, it was a little unclear to me which way is the correct way to reset this puzzle back to its starting position. That being the case, unfortunately I cannot guarantee that you will receive it correctly reset to the intended starting position for solving. 

These puzzles are part of a large job lot of puzzles I am selling on behalf of a serious puzzle collector friend, so please see my other Puzzle Paradise adverts for some rare and interesting puzzles. 

Please note: Payment by Paypal, bank transfer or Wise are all acceptable. Shipping fees and Paypal fees to be added after the end of the auction and to be covered by the buyer please. International purchasers from other countries are of course welcome, but final payment to be sent / received in GBP please. If paying by Paypal, a friends / family payment would also be fine by me if you want to save costs on the fees, I don't mind either way. 
I can provide postage quotes upon request if you want an idea of the likely cost before bidding. 
International customers please bear in mind you may have some customs charges to pay when the puzzle arrives in your country.
