DArcy_Echols_CoOriginal Kynock 505 Gibbs
Does anybody have an original 505 Gibbs case made by the Kynock of old ? Not the current Mfg. I would like to know the Rim OD and the extractor groove OD. Thanks

AfricanHunterI've got some downstairs. I think I have some originals and I know I have a lot of new ones that some jasper shortened and neck to .458. They would certainly give accurate base measurements. Do you want them or want me to measure?

Please send me an e-mail to echolslegend@comcast.net and I will send you some pics of where I'd like the measurements. If you have a decent caliper it will be very quick and easy or I can pay the cost of the shipping for the cases to come to me and back to you the same day.
Thanks
