.30 carbine double size trainer dummy cartridge wanted

HELP! I need at least one of the double size trainer dummy cartridges for the .30 carbine. Usually made of a plastic type material. Can use 20-30 if available. Also looking for the aluminum magazine for one of these. Thanks for you help. Contact me by PM or email below.

Have you checked Bill Ricca’s web site? He had .30-'06 I know last time I looked. Good source of info on these.
