Brackets welded in place I believe Graham, I hope they have it right very easy to get the axle off centre and askew. It only needs to be a few degrees to make it horrible.

The floors certainly appear to be alloy rather than stainless steel....I'll check on Monday.
The normal range of Trads continue to have marine ply floors.
