Just a word of caution on this advert...I ordered one from Epic Militaria from their website (the advert copy is the same as the Bay wording) and it is a Polish Lavvu and not a Plash Palatka as described. I complained to Epic and they said would amend the copy used, but it appears they are still using the misleading wording.Or possibly Russian plash palatka.
They are very similar
