    Shipped quickly via FedEx, arriving in reasonable time and fine shape. Very reasonable shipping charges, unlike those ridiculously high ones provided through eBay's system. Guitar is exactly as it was listed, pictured and described, no surprises included with it... No complaints! It wasn't de-tuned much, if any prior to packing it up, but it was packaged well enough and everything was OK on receipt. A good eBay seller with LOTS of interesting stuff to look at and buy. Take a look today! Thanks

    Delivered 5 days after payment, this AO 1234 was nicely packed and intact. Condition is good and as described. While a Bertrand lens is mostly intended for phase contrast annuli alignment, they are also handy for lamp filament centering..
