ID a Suntour rear mech?

This is a CL potential purchase. The rear derailleur reads, "Suntour XC" with an additional word after the XC. Can anyone identify this RD? I went through Velobase, but cannot be a match
Thanks.

Looks like this (Suntour XCT):

Yes, I think you are right. I dont think XCT is listed on Velobase; the site is down or I would check .
thanks for response

That derailleur does not have a slant parallelogram. Seems strange for Suntour.

It looks slant to me, just not dropped at the upper pivot

It's not on Disraeli Gears, either. Is it half plastic? Wow.

Not quite as good as XTC, but still.

I concur, its XCT, which was introduced in 1990. However, this is the less sophisticated, cost reduced, 2nd generation from 1991. It was the 2nd from the bottom of the ATB/hybrid component group line, only above XCU. I know that Bianchi spec'd it on their 1991 Advantage hybrid ($350), Giant on their 1991 Rincon & Nutra ATBs ($329 & $339), Specialized on their Crossroads Cruz hybrid ($329) and Univega on their Activa Country hybrid ($279) . But these these the only applications that I'm aware of among the major brands. It's direct competition in the Shimano product range would probably have been 200GS, which was spec'd more widely.

I was going to go after this CL bike for parts; but it sounds like this was lower end Suntour. Do you concur?

This is a post-bankruptcy model, after the SunTour name was sold to an unrelated company.

Yes, this is an entry level rear derailleur. I'm assuming the other components are comparable. Whether its worth it or not depends on the selling price and whether you have need of the parts. I'd expect most of the value would be in the wheels, which appear to be fairly decent, with 27", U-section, aluminum rims and QR hubs. These would at least make suitable replacements for a steel set on a 1970s, entry level bicycle.

SunTour's bankruptcy occurred circa 1995. XCT was introduced in 1990, then re-designed in 1991. In 1992, the rear derailleur's parallelogram arms were changed from silver to black. The subject derailleur matches the version in the 1991 catalogue (see scan).
