firstly i must say the model looks magnificent,
I am currently building one of these myself. My first endeavor at a white metal model kit. The material certainly has some interesting properties.
it is a bit different to a plastic kit in that it has surface pitting, and a few dross spots in the finish to contend with.
Did you have a problem with the fit of the rear piece of the front guard? I ended up squeezing it in a vice, and then re‑flattening the (now rounded) top of the part. (that was/ is the only major issue I have had to deal with so far).
I will be posting a thread on the build shortly... when I can tear myself away from the work bench long enough to get on the computer. LOL.
As this is a consignment build, I hope to have the thing finished within the next few months.
once again, your model looks fantastic. Stay tuned for my post.
