Another hoarder of freewheels here. I agree that 7-speed freewheels with an low in the 26t-28t range can be hard to find. Keep open the option of buying individual cogs and reconfiguring the gears. Sometimes 26t-28t cogs come up for sale. Loose Screws used to be a good source for indiv. cogs, but I think they went belly up. Boulder Bicycle sometimes is also a good source for nice vintage freewheels.
