I was contacted by Mike 08/12/21 and he stated that as of May '21 the quarry ceased operations and they are no longer producing Lincoln Limestone Silver and Red Bed.
I have emailed to state that we are taking them out of the directory, however once their new quarry is up and running to feel free to contact us for a new listing.
