Attention "Ausmanov and others: I have personally seen this exact (original) uniform twice, with scaled-down saber, etc. (but minus the Saint Andrew's order and small military badge), in an exhibition in the USA entitled "Nicholas and Alexandra," in 1998 and 1999. It is published (complete with full description and provenance) in the exhibit's rather large catalogue, on page 188/189 of the chapter "Costumes," illlustration # 324 as: " Child's Second Lieutenant's Uniform of the Life-Guard Engineer Battlion, which belonged to the Tsarevich Alexei Nikolaevich, 1910s." I have information on the publisher, etc. of the hard-bound catalogue if needed. I think it was later published in a soft-bound version as well.) Best regards, AP
