Hello. Can anyone advise whether there is somewhere some decals for 1:35 Waffen SS or Vlasov's Russian Liberation Army figures? I mean helmet signs, sleeve patches....

Archer has patches for the SS and Hudson & Allen has sets of uniform patches

Alliance Modelworks has a good selection of high quality SS decals along with PE badges and awards: http://www.am-works.com/store/lw35049-german-wwii-waffenss-uniform-insignia-devices-pi-70.html?type=jpg&pic=1

As the others have said Archers do some nice ones. Eduard do some painted etched metal ones which are good but don't buy them online. They're pretty hit or miss so you need to see them. I bought some which were spot on, nice and crisp yet another set were useless as they were smudged so were no use whatsoever and are destined for the bin. The only drawback I'd found with the Archers ones is the heat from your fingers can pull them off the sheet so they end up sticking to you if you try to put them on using the dry technique. They are however very nicely detailed, right size and even include cap insignia so they're probably the best ones on the market

Thanks
