    Loga 30 RC
    Swiss-Made Mercantile Slide Rule. Hard-to-Find.
    The
    Loga 30 RC
    Slide Rule is hard to find.  This
    specimen is in very good condition. Minor signs of use are visible on
    inspection -- small scratches can be seen on very close inspection; and the cork (or similar) backing on the knob is partially worn away (which does not affect function at all).  See photos.
    The cursor and the inner disc both turn smoothly.
    The outer diameter is about 12.5 cm.  The diameter of the outer scales is about 9.5 cm, meaning that the circumference of the outer scales is about 30 cm -- whence, presumably, the first part of the model name
    30 RC
    .  The "
    R
    " in the model name refers to the "
    R
    " reciprocal scale (Reziprokenskala).  Speculating, the "
    C
    " in the name may refer to the many commercial gauge marks found on the reverse (or it may mean something else).  Including the knob on the reverse, the overall "height" of the rule is about 16 mm.
    The cursor on the rear is coupled to the inner disc on the front, and facilitates turning the disc.  The leather case is in very good condition.  The instructions are included, and are in good condition. Because they do not fit into the case, instructions are often separated from Loga slide rules, and are especially hard to find.
    Satisfaction guaranteed! You may return the slide rule for a full refund for any reason, or no reason at all, within fourteen days.  Purchaser pays return shipping.
    Shipped within three business days, usually sooner.
    All slide rules we ship are very securely packaged.  Most packaging is recycled.  We have shipped slide rules all over the world.  No purchaser has ever reported damage to a slide rule in transit.
    Please ask if there are any questions.
    International bidders are welcome!  Any import duties are the purchaser's responsibility.  The description and price will be accurately listed on the customs declaration when the rule is shipped.
