Hi Tracy, it is from the Trilex series from Scaleart. They have the 6-hole version (which I ordered) and the more modern 10-hole version. Both are metal casts.

The pictures in their webshop don't really show the detail. I was pleasantly surprised when I unpacked this one.
Couldn't find the 6-hole version for the front axle. Turned out that you have to order the front axle with them so they are under rear axles (no wonder I had a hard time finding them

)
