The version they made had the tail made in the english system and the rest made in the metric system. When they tried to join the two halves, they did not fit. Also they copied the boeing logo in the rudder pedals.
Mmmm. I'd like a source on that. Sounds to me like some comforting American invented myths. Front end didn't match the back end? That's a bar-tale.
First 'the english System' would be 'Imperial measures', I presume - I can't see the Russians using it - They were using Metric. The issue was the B-29 was built in American materials and measures, which IIRC are a mixture of Imperial and US measures, none of which would work with Metric directly.
If the rudder pedals were cast, then using an original, logo and all, as a master for a sand mould makes sense, it's quick, and does the job. You'd have to physically remove the logo from the 'master' or within the mould - but why bother?
I don't know how B-29 pedals are made, but Vultee Vengeance pedals are cast (I think) from those I was looking at recently. Engineer input welcome!

The Soviet Union used the metric system, thus 1/16th inch sheet aluminum and proper rivet lengths were unavailable. The corresponding metric-gauge metal was thicker; as a result the Tu-4 weighed more than the B-29, giving it less range and payload.
Interesting discussion (after the interesting article) here:

You choose your favourite myth from that lot!
On topic, the full history of the B-29 development and introduction to service was a pinnacle of mass achievement, effort and guts, overcoming numerous major setbacks and new problems. Because of the newness of 'whizzy' things like jets, IMHO the Boeing team didn't get the credit they deserved.
To answer MB's question another way, Boeing went from the 247, 299, B-17 to B-29 in very few years. Each was a major step upward in capability
and complexity, yet utterly replaced the previous type (excepting the civil 247).
