I thought you probably were going to add it, seeing all the other intricate detail you have put in.
As regards the pull handle, it might be visible looking in the top hatch, or through a side door. And you'll know it is in there.
My bottle is actually OD green. It was NOS in a box (new old stock, as in it was still unused and in the factory box, but dating from 1971).
I had another, that ratty looking green one, which came out of another V100 that colour, so that's how I kept mine.
The bottles came in either green or red, and there seem to be no rules for installing either colour in service, they just put in whatever colour bottle came out of the box.
I had a red bottle too, gave that one to either Dave (HellonwheelsV100) or JimK. We traded a lot of V parts with each other since we were all doing restorations at the same time. Jim got the second actuator in the picture. I don't remember who got the other green bottle.
Even though all my fire extinguishers are originals from the early 1970s, all passed inspection at a fire company, so all are filled and working.
Cheers
