Home built traction trailer

So I've been building a Road Loco for about a year or so, and over lockdown last year started to build a trailer for the engine.
Hope this is acceptable as it's not an direct STW product....
It's a step frame type trailer, the tires I got FOC from work and most of the steel I bought.
It's mainly TIG welded construction with a few bolts here and there.
The turn table for the front axle has been the most expensive single part.
It has got a simple parking brake system fitted, just a square steel tube that presses on each tire.
Hers a few pics of progress so far.
