Bottom 3 characters look like 679. Others can't make out

I just acquired this.  I would like the characters translated if possible.  

Up for sale is a group of Russian/Soviet era Propaganda Posters. These are reprints (hence reproductions) of the actual posters from the 1930s through the early 1950s. A good selection of posters that measure 16 inches by 11and ½ inches. Some of the posters have some slight stains in the corners but they are in very good condition. There are 19 posters total. The original package had 21 posters so 2 are missing. I will cross out the posters missing from the group (Xs in BLUE INK). These were printed around 2003.   I am asking $22.00 for the group plus $6.00 shipping. ($28.00 total)   I will not ship overseas.   Payment methods I will accept are PayPal (F&F) or buyer adds 4% and US Postal Money Orders.   Thank you for looking   Leigh 

Welcome to the WMF!

Glad to have you aboard,  LeadSpatter. Ken

Thanks for that. I hadn't considered such possibilities 

I’m old school generation war memorabilia collector, competitive shooter, range officer, and match director from U.S. deep southern cornbread born raised who has closet full of trophies since mid 80s long before smarter mobile phones than I existed, lol. I spent my childhood and adulthood working daily and help take care of my elderly great grandparents, grandparents, mom and dad before they crossed over to our Lord and Saver! I realized at a young age every time we lose a elder family member we lose a World Historical National Library! Beyond all doubt if we don’t fail on our responsibilities as parents, grandparents, and great grandparents to pass along our past elders experiences to our future generations, then only then have we achieved success! The countless hours I spent from childhood until my last elder family member passed away years ago for my only son to learn is truly endless valuable knowledge to pass onto to our future generations!  I do have several collectibles I’m seeking knowledge for!  I’m NOT here to take advantage of anyone as we all have our own crosses to bear in this life or the next!  “Those who don’t learn history tends to repeat it” - Benjamin Franklin    Thanks for your Time and Consideration, LeadSplatter

The top photo shows a better picture of the liner, you'll notice that there is no joint in the back of the liner where the liner bridge joins, which would have been stitched together.

Practice bomb.

I agree with Marshallj,,   Some type of drop tank..   Leigh 

My guess is that is an external fuel tank. 

Many years ago a friend and I stumbled across this and, in retrospect, rather carelessly took this pic. Would anyone be able to shed any light on it please? Thanks
