This upgrade provides a 1//32 scale improved Oxygen (O2) tanks for the HK B-17. It comes in two different options, with four each (eight total) O2 Tanks. Four tanks have mounts and brackets, and four are just O2 tanks with no brackets or mounts.
When held next to the kit O2 tanks, the size difference is very noticeable. The HK tanks are all too small; the Detail2Resin tanks are correct. Remove the tanks from their pour stubs, then primer with gray or white , (I used Tamiya White) and then paint gloss yellow(again, I used Tamiya Camel Yellow) . Weather a bit, then paint the mount straps silver or steel; the mount itself was usually interior green.
As this is a basic seat with all parts molded in place, the overall work goes very quickly, with no parts or additions required. The detail really stands out once all the drybrush work has been accomplished. Much easier than making your own mount and straps out of foil In my opinion!
