The later kind, made only from c. 1918-1920, was a tubular pitman instrument -- similar to a normal electro-pneumatic M=F6ller, but with tubular primaries. These are very fine instruments and can be restored the same way as any other M=F6ller.   Unfortunately the majority of tubular M=F6llers, built in 1876-c.1915, ar= e of the bar-and-membrane tubular type. To cut a long story short there is a leather membrane which has to seal and in which the tension in the leather is critical. The weather inevitably causes the leather to expand and contract, and bang goes the adjustment. Most people who have tried to restore one of these instruments have ended up with a nightmare of ciphers and dead notes. It might theoretically be possible to restore one satisfactorily if one used totally stretch-proof leather.=20 Kangaroo might work if one were able to obtain a satisfactory and consistent supply of it, which no leather supplier I know who has attempted it has ever managed to do so, at least in the long term. The late Jim Akright of Baltimore claimed to have satisfactorily restored a M=F6ller bar-and-membrane tubular using graded thicknesses of rubbercloth. Even when working properly, however, the bar-and-membrane chests are extremely unkind to pipe speech -- resulting in a sound rather like the valve bounce of an early Wicks direct electric.   My advice, therefore, to anyone who has a M=F6ller tubular with bar-and-membrane action is under no circumstances to attempt to restore the chests. If you have such an instrument with good pipework, get some secondhand chests from the Clearing House or elsewhere and use those instead.   John Speller, St. Louis, Mo.

One bit of= humidity change, and it's time to head over to the Hammond! There is a "pre-stretched" grade of pneu leather that you're suppoed to use in the membrane-and-bar chests, but I can't remember what it's called. Surely there must be a better synthetic substitute with all of today's technology!!   DeserTBoB
