A few redundant metal flue pipes needed urgently in London for exhibition

[Lucien Nunes]

A bit of an odd request this, but hopefully someone here might be able to help. To complete an artwork, a dozen or so metal flues perhaps 4-6' in length are needed in the next day or so in the London area. Does anyone have an incomplete or damaged rank of no further use musically, from which we might be able to obtain them. Conventional appearance is important as they need to be recognised for what they are, although musical character (or lack of it) is not! I have a few ranks answering that description but unfortunately none of them are accessible within the available time.

Thanks in advance
