Meanwhile, some painting done on the V2 - I am still suffering from the paint lifting, but have decided to persevere anyway.
I am doing the Gezackt pattern camouflage from 1943.

The rear fuel tank was a large lump of resin, it had attached to it a large lump of resin that had to be removed with a razor saw and then sanded flat - quite a chore.

More cleaning and sticking together.

Great stuff, you are certainly into this area of modelling now - is this your current sub-ject?

Especially for Mr Ward, here is a summary of Stoff.

STOFF
A -Stoff – liquid oxygen (teargas was called this in WW1)
B-Stoff – ethanol and water mixture
C-Stoff-
Methanol CH₃OH   ~57% by Weight
Hydrazine hydrate N₂H₄ · H₂O   ~30% by Weight
Water H₂O   ~13% by Weight
Catalyst 431   K₃[Cu(CN)₄]     potassium-cuprous cyanide coordination complex


F-Stoff – Titanium tetrachloride
K-Stoff- methylchromoformate
M-Stoff- methanol
N-Stoff – chlorine trifluoride
R-Stoff or Tonka: 57% monoxylidene oxide / 43% triethylamine
S-Stoff: 90% nitric acid / 10% sulphuric acid or 96% nitric acid / 4% ferric chloride (The ferric chloride acted as a catalyst.)
T-Stoff- hydrogen peroxide mixture
U-Stoff-dinitrogen tetroxide
X-Stoff-tetranitromethane
Z-Stoff-calcium permanganate / sodium permanganate / water

Now that you are fully Stoffed, its back to modelling. Sorry as an ex-chemistry teacher I still like to spell sulfur as sulphur (or is it my Britishness?)

The chassis comes together.

Life has been getting in the way of modelling.
I have had a disaster with spraying the V2, after masking I am afraid the paint lifted in areas. I tries to rectify this but am most unhappy with the result.
At present the rocket is in a black sealed plastic bag covered in Mr Muscle Oven Cleaner.
I will remove the paint and try again.

Meanwhile, I am making a start on the Opel Blitz T-Stoff Tankwagen. This is the Italeri Opel Blitz truck with resin additions. I purchased the whole thing from Azimut models. They send the resin additions and the bits of the Italeri kit that are needed.
Here are all the bits.

The Opel Blitz Ausf S Kessel-Kw. 3t tanker carried the highly-volatile T-Stoff (85% hydrogen peroxide 560 gallons & 15% water 80 gallons) that, along with permanganate, powered the rockets steam turbo fuel pumps.
There was also the alcohol B-Stoff tanker version, which could carry 770 gallons. The vehicle was equipped with a rear pump, capacity 66 gallons per minute, and a hand pump 21 gallons per minute. Weight loaded 13,000 lb. It would require at least 2 tanker trucks to fill the large alcohol tank on each V2. Three trucks could fill 2 rockets.
