Losmandy Aluminum Motor Covers, machined by Losmandy. Adds the right touch to a great looking mount. Replaces the stock vinyl motor covers. (I'm not sure if these are compatible with the Gemini motors.) This is Losmandy part number AMC which retails for $90.
$45 plus $10 shipping, insurance. Will ship within the US only.
The photo below has jpg compression artifacts in it that look like water spots. The motor covers do not have spots on them. They are in near perfect condition.
