HH special and heavy weapons on other firstborn marines

[roryokane]

Quick question, chaps.

 

I’ve got some extra heavy and special weapons (complete with arms!) from the heresy kits, and some firstborn marines with no weapons. I know the arms aren’t cross compatible (hands on weapons vs not on the old arms), but do the kits fit wholesale onto say, Mk IV or 40k tactical squad bodies?

By fit, I mean without lots of chopping or without using lots of green stuff.

 

I had a quick squizz with the search function and more broadly and couldn’t find an answer. 

Would like to add some old-style HH weapons for variety to the classic 40k Mk VI/VII/VIII tactical models (and the Mk IVs too, I suppose!), but wanted to see if it was feasible without too much work!

Tale of Painter's review has some pointers - don't know if that's any help?

I added the new mk vi beaky arms to the old mk iv Maximus bodies with very little  issue. True I was giving them bolters, but I don’t think special weapons would be a lot different. I plan on adding a heavy flamer and a Volkite Culverin I got from a bits store in the same way. 

Now I dug these out thinking they were finished but I see they need eye lenses doing and decals matted down - so back to work!

 

I don’t think I needed green stuff (shoulder pads cover it), but a little bit of ‘give’ at each joint might be required, I’m not convinced the mk vi flat areas at each shoulder are completely parallel as they are in the firstborn kits.

I put some of the MkVI arms and special weapons onto MkIV bodies.

 

Some of the pairs of arms were not a 100% flush fit, but there was enough contact area between the arms and body for a stable glue joint, and any slight gaps between arms and body were covered completely with shoulder pads.
