Hello Jack D. I can not tell you any thing about your question.
But welcome to GBO forums, Might be a good idea to post down on
Marlin site.
Never post your E-mail addresson a Open forum, you can remove it
by hitting edit top right of your post. You must be about my age
by your e-mail address. I am a Korean Vet also. old Fxxt.
Good luck Marv.
