I''d say it reproduces almost perfectly the first "B" model (for those who could dislike the quality of plastic material, rest assured that the originals weren''t better). Not tested yet, but it''s so a simple device that there''s nothing wrong which couldn''t be easily fixed if not working properly. I don''t like the WPG signature on the bottom, but I have to say that in the case of TL-122B it has the glance of a period marking (not at closer inspection, obviously) I''m satisfied with it, You can carry it around the battlefield without mercilessly ruin a precious original, which is the purpose.
