Well, after fitting two 20 ga barrels to a newly acquired case colored SB1 along with BC furniture, I have completed several months of wheeling, dealing, hoarding and acquiring and now have complete platforms for my current H&R collection:
My most recent build: 45LC/454 Casull DIY Stutzen

My Long Range Handi in 30-06

And my back up Grouse gun 26" 20ga BCSG with Invector chokes that will serve with the 28" VR Topper DeLuxe Bull Barrel as my Southeast NY Slug Gun :

I'm glad winter seems to have come to a screeching halt so that I can get out and do things instead of conjuring up new projects!
If anyone has a case colored receiver, here's a good tip for protecting the coloring which will otherwise wear off fairly quickly. I got some "Case Colour Lacquer" from CSMC (and also got on their mailing list which is very bad for the wallet!). It's a clear lacquer (and I'm sure available from cheaper sources - I won't be surprised when Tim tellls me there's a recipe for home brew in the FAQ) that you brush on over the case coloring and then smooth up with a little steel wool when dry. Helps deepen and bring out the case colours and protects them from wear.
