Leadpipe for B&S Imperial EEb

[Grommit]

I'm going to put this question out there in hopes that somebody can point me in the right direction. I have a late 1970's B&H Imperial EEb that has had the original receiver replaced with a larger more contemporary receiver to accommodate the American shank mouthpieces. The horn was modified before it came into my possession. I am not an expert in these matters but I am wondering is this generally a good solution or is it better to fit a modern leadpipe from a Besson 981/2? I like the way this horn plays but there are some challenges that I can't help but feel may be caused by the receiver. If it is better to replace the entire leadpipe with a modern one are there any out there that someone would be willing to part with?

Any insight would be welcomed. Thanks.

What are the challenges? We need more information before we can recommend anything. In the meantime, have you tried either a Wick 3L or a Bach 24AW on the horn to see how it plays with either of those two traditional mouthpieces used with an EEb comp?

I'll try both of those mouthpieces and see what happens. If things are just the same I'll list the issues I'm encountering.
