I've lost a few parts for my silver Melita and find the price quite acceptable
When the Bigsby was added to my 6128 in 1959 I was upgraded from the stock Melita to the bar roller. Never found conclusive advantages either way. Discusses selling with ?George? Grugh a few years back and he was generally negative on any changes from original so I've been on the lookout ever since. I do recognize the general attitude of resellers to expect better than mint condition to widen their customer base and fee.
Please to let me know in no urgent manner if you wish to proceed or not . I would prefer using Paypal and USPS. May you get maximum sustain from 2013 happiness.
