The Cyclo “OPPY” was launched in 1938 as a racing gear.  It continued in production until 1948 but 6 of its 11 years of production would have been lost to the war, so really this gear was only around for a short period of time.  You can find more detail about it in "The Dancing Chain" book.

I have stored this gear for many, many years.  The gear itself is absolutely perfect, complete with correct lever and double cable.

This is an exceptionally rare opportunity to own one of these gears in such an unused condition.

Note shipping costs, which include the fees that sellers get lumped, even though the costs are unavoidable.  Any cheaper shipping method that can be found will be refunded to buyer.
