I have a photo of a gutta percha brown Columbia recorder, is there anyone who could give me an idea if it is a reproduction? I will send the photo to any one who can help.

Message-ID: <[email protected]> ALL NEED to be aware that main spring replacement is something for the well trained and knowledgeable individuals. I was visiting a friend this weekend and he shared a story with me about an antique dealer that would not take any advice about getting this done by someone that had plenty of experience. Well, the antique dealer felt that if it could be done, he could do it. About two hours after buying a new spring, the man had lost an entire finger and had come close to having the jugular in his neck severed by a loaded spring. The kinetic energy is unbelievable and can be deadly! So, all need to take care. Sometimes it pays to have someone do this. Once done, the turn table will be spinning for another 100 years. Just because a brain surgeon can perform brain surgery does not mean just anyone can. Just because the Edison instruction booklet seems clear and precise does not mean that this is a walk in the park. Just some food for thought folks!

(Edison), with the name Chatwood also on the dial? Would a date of ca 1905-06 be about right? The sloping metal enclosure is an iridescent red color and it has a circular 'felt' backing. \ Allen **************Need a job? Find employment help in your area.

Use multiple vice-grips to manipulate the coil Installing new spring: 2. The new spring usually installs without the uncoiling of the spring from the piece of wire which holds it coiled. You can just slide it into the spring barrel in the proper position for the spring to grab the retaining pin.
