Thank you Gene. On the upper ramp I used plastic, cardboard and metal pins. On the lower one I used some metal bars, I think they are white metal from old kits.
Thank you guys for the suggestions, but I already contact HRM, and some store that sell his resin, but, since last summer I have no news from them. Thanks Steve I will contact Replicas & Miniatures!
Thank you all guys!
@ Matt Bacon, for now it is on a box in my closet. An probably I should keep it there, I show this build in some forums, and some people were upset about my Humor...
