Not only the font, but also some of the labels used for modifiers are not correct in terms of what they say if you try to mimic old Cyrillic keyboards. For example, Нчл and Кнц (Home and End) on the old keyboards I saw were saying НАЧ and КОН (short from Начало and Конец), Алт should have been АЛФ, etc. But nonetheless - I would prefer you left it as is, I really love how these things look like - all these "Забой", "Ввод", "Регистр", "Заглавные" - are just beautiful (in the exact font you have it in, with infographic where applicable), even though not technically authentic. If on top of that you price it well, I would be definitely buying it.
