No.37 stays in my collection; duplicate No.15 is available.
I know the history of the inventory, prior; some pieces traveled with one appearing in Seymour's and to later sell in a P&P sale in 2017, and a few other pieces maintained in the South of France for several years before some of them made it to eBay selling at various levels way below published prices, while one damaged oval sold at auction in France last year for 20€.

Though the market is not what it used to be when I was selling MOP plaques at $500, $800, $1200 and $2000+ each, some of the quality material that rests in Spain, in strong hands, is moving at some pretty lofty levels in the past two years. Bravo to them for not adding to the killing of the MOP market.
