Is it a staight cut gear?? If it is, go to an industrial supply house that sells Browning products or power transmission products. They can usually get off the shelf gears that might work , may have to bore or sleeve the hole or make them thinner, drill holes etc. If its an oddball, you will have to make it yourself, scrounge at scrapyards or be nice to your local friendly Machinist. Just dont be surprised that you cant do it for 50.00 and cant have it in 2 days. I have made at least several gears for odd ball stuff, you are looking for a low speed gear and accuracy isnt the big factor. email me a bit more info.. dodogas@teus.net might be able to give you more info, Frank
