Sheridan Back Bottle ASA with RVA, Dummy 12g

[Diomedes]

So...anyone have a Sheridan back-bottle ASA with an RVA? How about a dummy 12g? Thinking ahead on a marker that's arriving soon.

I think so... but the side tap is 1/8"-npt, not whatever Sheridan normally did. It's off a backbottle Typhoon I converted to vertical air.

1/8 npt is preferable - this is to keep in my back pocket for a Squall I have on the way. For if (when) I get fed up with the underbarrel 12 gram changes.
