I think the probability is high that they, at some time, belonged to the Town of Poole, although legally they may not now belong to Poole. In the 1820 Poole was almost bankrupt (what’s new) and could be when the unpaid Poole Town Clerk, Thomas Parr, seized all the assets in lieu of payment of salary and they were removed then, some were "regained" but not necessarily all. It’s good to know they may still exist and have not been melted down for the silver, lets hope Poole can regain them and use them again in Poole
