Looks great
It's at least 6.67% NOS (if I went through the thought process correctly).

Re: New RR-1 tank
Thanks for the compliments.
The cylinder on this one isn’t correct. It should have just 2 transfer ports with SPI. The cylinder that it has on it is a TD .049 cylinder with two transfer ports and 4 boost ports. It doesn’t have a #4 stamped anywhere though. It is tapered too.
I don’t think TD cylinders were out when this version of RR-1 was available.

Oh, well I couldn’t tell that from the photo, but that’s a nice early #4 so it looks correct on the outside!

Re: New RR-1 tank
That looks very nice there. Is that also a new backplate, or did you just polish up the original? Looks very shiny in the picture.

Re: New RR-1 tank
It’s an early backplate that is zinc dichromate plated. The backplate was in very good condition on this engine.
