Urich:
You might wish to review several of the recent HMCS Snowberry "threads" posted in this forum for access to worthwhile links on corvette color schemes. While there, check out the small fortune in obsessive-compulsive photoetched detailing available for the corvette. You can just about end up with a complete vessel (not necessarily a corvette) with the flag sheet from your model as the only part from your original model purchase!
You might also be interested in viewing the Tupolev G-5 Russian Torpedo Boat kit in 1/72 scale by Interavia. It's available from Army Book (www. armybook.com) at $9.95. That price sounds good, but they add some "mysterious" tarrifs, shipping, etc. to make it somewhat "pricey."
I haven't built one, but would be interested in anyone's opinion of the kit.
