George, you have more patience than I do ... and likely, more talent too! I'm not much into scratchbuilding, though I have done a bit when it comes to replacing/repairing parts, as I'm sure most of us have.
This is a totally new design for me, so add my name to the "Never Heard Of It" group of iModelers. Thanks! I always enjoy looking at "new" designs.

Looking great David! I can commiserate with you on all the work to match things up, as the Savage I'm working on is a Mach2 kit, and almost nothing matches or fits! I have NEVER had a larger pile of styrene shavings and dust on my bench (or probably in my lungs)! The things we do for projects we really want to have in our collection...!

David, it is looking great. All the RS kits I have built have all resisted completion, some to the point of flying into the circular file, but they have all looked good when done. Congrats on your perseverance. At some point they just become a quest...

Paint! Decals and Missiles next!

Fiddly Little Missiles x 4!
Fortunately Tamiya extra thin works well with this plastic!

I did not realise that it had been this long - but here are some pics of progress so far!

The decals really make this look cool, David (@davem). Glad to see your models again.
