Yes the Eastern Express range is about 50% x Frog, they seem to have managed to pull these together under one roof -
previously being released from many various Russian kit companys, Novo, DFI, Tashi, ect from around 1980 and the overall quality is much improved over those issues, considering the age of the moulds.Their range includes Civil Aircraft including a few x Frog and also loads of 1:35 Amour, the origin of which i cant say.
Of the jets, one or two are very early x Hasegawa moulds that Frog used in their range - a good source for classic kits and some Aircraft types not found much elsewhere, fit and detail
may leave a bit to be desired tho as mentioned above.........
