I checked out the dealer site suggested by jdmoran (www.gessweinmotors.com)
and looked through his Imperial inventory. One of his 61s (with 20,000
miles - yeah, right) has a photo of the engine compartment and it clearly
shows the exposed-bellows type of brake booster. My 57s had these but my
61 has the enclosed can type bellows. I don't think I have seen the
exposed bellows on another 61.
Fellow 61 owners (and near years), what type of bellows do you have? My
car is an early production (#394) so it doesn't seem to be a parts
carry-over issue.
