Some walkaround pics may help as well.

I had a similar idea some years ago when I photographed a CAT Scraper in Grafenwohr. I used the drawings on US Army Technical Bulletin on NATOflage. But I still need to find out how to make the wheels.



Warning: This thing is really huge!
Btw, this is good old scratchbuilding, nothing with 3D printing. :smiley:

Thanks very much. I actually saw this site during my search but it seems they mislabelled the 621G as the scraper in the drawing has a different rear design compared to the 621G

This looks very good. Can you share the drawing from the US Army bulletin please

Yes of course. When I find out how to use my scanner, I post it here.

AFAIK the one pictured in this bulletin (TB 43-0309) is a 621B model…

Frenchy is right. But I have the neccesary pics to build a 621B if you don´t mind.

Please share. 621B is also fine

You are welcome! May I ask what you plan to build?

I plan to build an RC 1:35 scale M1070A0 HET and a 1:35 Scale 621G scraper. The scraper will be transported by the HET.

Is it only me or does anyone else prefer the looks of the M1070A0 to the looks of the M1070A1. I think the M1070A0 looks more badass

If anyone has pictures of the HET carrying a scraper, please share. Such pictures are so rare online. I found only 2 or 3 of such pictures.

Nope, you only posted once. Here is what you posted.

“your build sounds pretty cool - regarding the HET, yes! I like the alternate hood too. I tried to build one, with limited success:”
