Hi Bonnar Bloke, I have owned a couple of alloy versions of the Victa steel chassis with the same handle bolts on top and they seem to do alright as there is no flexing at the mounting points like the steel version, where you can feel it bending as you push it. This doesn't occur with the alloy version of this mould.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
