S7 wagon competition at the A.G.M

[Michael Osborne]

Now my newsletter has arrived I can see the results of the last wagon competition. Congratulations to Peter Drost for winning the scratch built category with a fine entry.
I asked on here in May about the difference between a tank wagon built for oil products and one built for chemicals ?
I have built a tank wagon but the liquid inside was for chemicals and not oil so I did no enter.
Looking at Peters fine model I cannot see the difference between the two. They both look the same to me.
This may seem like sour grapes but I am more amused by this strange anomaly.
