Hi Pat,
Thanks for the review, very useful. I bought this to go with the T16. Not the Full Monty but a very cost effective way to get a decent towed 6pdr.
On the tyres I ran an emery board quickly over the one on the right, gives a slightly broader tread which I think is what Geoff meant as it helps take the 'shaprness' off the tread.

Cheers
Al
