This offering is for one set of new-old-stock Shimano 600/Ultegra index (or SIS) capable shifters (Model SL-6400 in the braze-on model). These shifters incorporate Shimano's second generation index shifting technology (introduced in 1989), which appears to improve upon Shimano's earlier design by adding the 7-speed index shifting option. They are not as nice as Shimano's top-end Dura-Ace down tube shifters from this period, but still a very good quality down tube shifter set (and extremely rare in new-old-stock condition). Some of the detailed specs include...
Index shifting compatibility: 6/7-speed (with Shimano branded or compatible freewheel/cassette)
Friction shifting compatibility: Several options (most 5/6/7 speed freewheels/cassettes)
Mounting bracket/spacers: Braze-on model w/curved spacers (refer to discussion below)
Weight: 107 grams (including mounting hardware and cables...just as pictured)
Other notes: The left-side shifter is designed for friction-mode only, so it should be compatible with most double/triple cranksets.
The levers have an all alloy body and are painted in a gray enamel (that is actually probably darker in color then it appears in the pictures). Please also note the last picture in the sequence and specifically the small, black, plastic/resin pieces. These are relevant small parts that we do not always find with these shifter sets. More specifically, the small rectangular-shaped pieces are dust covers that seat over the cable heads (located on the inside edge of the lever body...so the side of the lever body that faces the down tube). Additionally, the semi-circle-shaped piece is needed to adjust the right-side shifter from a 7-speed to a 6-speed index shifting environment (and the installation of this piece is illustrated in the pamphlet included with this offering). In other words, if the shifters will be operating in a 7-speed index shifting environment, then this small, plastic/resin piece will not be needed, but if operating in a 6-speed index shifting environment, then the piece will need to be installed.
The few sets we have are retail boxed and show quite well...and this includes the gray enamel finish, which has been well preserved. Also, each set includes the full complement of shifter cables and mounting hardware...although please refer to the note below for more specific details concerning the mounting hardware.
Down tube spacer discussion...
If you look closely at the pictures to the left, and particularly those that show a close-up of the mouting hardware, you will notice the two spacers/adapters used to mount the levers on the frame's down tube shifter bosses. These spacers have a curved profile, which means they are compatible with vintage steel frames with the smaller down tubes (relative to some of the oversized down tubes made from other materials). More specifically, the curve in these spacers/adapters seats very well around a 28.6 mm steel down tube at the shifter bosses...resulting in a nice/clean look with mounted shifters. The one additional mounting specification worthy of mention is the square-shaped mounting platform noted in the last picture in the sequence to the left. This square-shaped platform measures 12 mm x 12 mm and should also be recognizable at the base of braze-on bosses (on a frame downtube) to ensure this shifter set will seat properly once the mounting bolts are tightened. There may be other applications where these curved spacers will seat fairly well, but the vintage steel frames are the best example we've noted from our own experience.

Note to international customers regarding shipping...
We apologize to those that feel some of our international shipping charges are too high. We only charge actual shipping rates, but once an order exceeds a certain amount, we hesitate to use the least expensive US Postal Services First Class International service. We feel this way, because this service is not trackable or insurable...so more risk of loss. We prefer the US Postal Services Priority Mail International service for more expensive orders, because this service is trackable at USPS.com and insurable...so less risk of loss. Unfortunately, this service is more expensive, especially for smaller/lighter packages, relative to the First Class International service. We are sorry about these higher shipping costs, but hopefully our notes help to explain why this is the case.
Note to international customers regarding customs...
We also apologize to those that feel their country import taxes, duties and brokerage fees are excessive. As a small US business, we are required by customs' laws to declare each order as a retail sale. Additionally, the declared order value must be equal to total store purchases and/or winning auction bids (less any shipping costs, as these are not considered in the declared value). As a result, each customer will be responsible for paying his/her own country taxes, duties and brokerage fees, which will be collected upon delivery. Again, we apologize for these additional costs, but we cannot afford the penalties and fines that come with breaking customs' laws...so we have to strictly abide by them.
