Might this have been Henry Streeter Sand & Ballast? Brown logo, Dodge tippers I believe.
No, I don't think so and not St.Ives either!
I seem to remember grey or green trucks with orange lettering. Ham River trucks were (I think) grey with dark green (or was it black) lettering - this is seriously straining my memory files - may need a defrag!
Whilst on this trivial pursuit I do recall that the Ham River Gravel Company was named after the village of Ham on the River Thames and not any 'Ham River'. Strange what the memory absorbs and tucks away waiting for a prompt.
