Hi!
It's great to see that a new braille scale model maker appears on Armorama
From an other forum: the sprues for the Kfz 13 and Kfz 14 are the same, only the decals and the instructions are different. The frame antenna has to be built from wires (only the mounts are included in the kit).
Personally, I have built one kit from ACE. It had a rather poor molding quality, but had all the details one can hope for. Nevertheless, this kit already appeared on my shopping list, I'm sure that with much work it will turn into a great model.
