Archer Transfers do some 1/16th Items.
Having just branched out into 1/16th, I've found a bunch of US vehicle & Bundeswehr stuff from a German Company PEDDINGHAUS-Decals 1/16th, postage was just about bearable for Germany to UK.
This link is from UK Ebay, 1/16th items from the US ebay.com site were a lot sparser, so you may need to find a US distributor.
Direct link to their German home page peddinghaus-decals Germany
I Also bought a set of Resin printed US WW2 sidearms from Ringo Resin UK.
All I did was a Search for 1/16 in Ebay, which turned up a lot of decals, sidearms & stowage.
So a growing market.
