Examples of pean arms:

Roome of Newport – Argent, a fess pean, in chief a lion passant gules, langued azure.

Muntz – Pean, on a mount vert a swan rising argent charged on each wing with a trefoil slipped of the second; in chief, a staff raguly erect between two estoiles Or.

Institute of Bankers – Pean, an annulet of chain Or; on a chief gules an open book of the second leathered sable between two bezants Or.

– Scans from plates by Norman Manwaring M.L.J., M.A-W.G.

If anyone is familiar with a coat of arms bearing the pean fur I would be most obliged if they would share it!

These are beautiful, particularly the first one.
