More Pewter Marks was the first ‘follow-up’ volume to Cotterell’s Old Pewter, and a ‘must have’ book for the collector. Published by the author CA Peal in 1976. A fire at the printers soon after publication destroyed the proofs so no more copies were ever produced. Hardback book: 117 pages.
Addenda to MPM was published after the author published MPM, and received so much new material that he decided to publish a companion volume in 1977. Booklet: 33 pages.
