I do think there will be a transitional period which is neither exactly communistic nor capitalistic, but that is not implied in the sentence you quoted. And it certainly doesn't follow that because we recognise that a transitional phase will exist which has the imprints of both capitalism and communism, that therefore the Soviet Union was an example of such a transition.
Centralisation of credit wasn't a policy objective of a proletarian dictatorship.
"Centralisation of credit in the hands of the state, by means of a national bank with State capital and an exclusive monopoly." (Communist Manifesto).
The 'Demands of the Communist Party in Germany' of 1848 have a similar demand: “All private banks will be replaced by a state bank whose bonds will have the character of legal tender.”
“This measure will make it possible to regulate credit in the interests of the whole people and will thus undermine the dominance of the large financiers. By gradually replacing gold and silver by paper money, it will cheapen the indispensable instrument of bourgeois trade, the universal means of exchange, and will allow the gold and silver to have an outward effect. Ultimately, this measure is necessary to link the interests of the conservative bourgeoisie to the revolution.”
Marx and Engels aren't talking about proletarian revolution, which obviously wouldn't require the support of the conservative bourgeoisie.
The 10 planks of communism were communist demands for the completion of a bourgeois revolution. They did see this, at this point in time, as a process of permanent revolution that would result in a proletarian revolution, which they didn't see materialise to their disappointment. But the [proletarian] interjection of your is incorrect.
It's completely laughable to see some 'Marxists' like Cockshott and Bertrall Ollman (iirc his name correctly) use the 10 planks to map out socialism. It's such a sham, demands explicitly linked to facilitating bourgeois trade and bourgeois revolution used for socialism. But that frustration aside.
