Hi i have a bottle of Madeira without the producers name

Any help would be appreciated

For all of your queries and sales, some photos of the bottles might help. Style of lettering, shape of bottle, type of seal, etc. can all help in identification. As it is, I don't know much about older Madeira bottlings, but others might.
