A RARE VINTAGE CRYSTAL LATTICE STRUCTURE MOLECULAR MODEL TEACHING AID, WITH 23 PAINTED WOOD BALLS EACH CONNECTED BY SPLIT ENDED BRASS RODS. Each ball is drilled with 26 holes for multiple construction possibilities by students. AI suggests this may be an early example produced by Crystal Structures Ltd (Cambridge) c.1947 founded by Dr Nora Wooster, but I haven't be able to find any comparable example. MAKERS MARKS - unmarked SIZE - approx. Balls 2.5cm (1") , rods 7.5cm (3in) long Model currently as constructed : 19.5cm high 10.5cm wide CONDITION - VERY GOOD (a few small paint losses, patina to brass rods. Please see photos) Items will always be packed with great care and proof of posting obtained, combined postage discounts will be calculated on multiple purchases where possible.
