I am looking to buy an antique banjo barometer and am located in New
England.  I can only find dealers in England that have these
instruments available.  Is there an antique dealer nearby I should
contact?  Or do you know of buyers willing to source the barometer
from England and guarantee the shipment and quality for a nominal fee?

Hello,

Here is a place is Mass. that has a large selection of barometers

Hope this helps, I am not sure where in New England you are, and how
far you are willing to drive/fly for this, but if none of these are
close enough, please let me know.
Thanks,
