Help Identifying Tonti

[ozarquebus]

Seller is sending me pictures of a motor and frame, but I can't figure out what they are and he does not know. Here is a picture of the placard and the front of the engine.
He says it was a cop bike.
Number could be 101592 or 107592 even though he thought it was 101692. Exact serial number doesn't really matter since there is no title.
Just trying to identify model and I think it is an 850, but not sure. He wants 300 bucks for motor and frame and some misc parts

Can you get a picture of the engine number? Should be on the  left side of the block. VE, VG, etc

It is starting to look like an 850 Cali Police in which case it will have chrome bores, right?

 Chrome bores were stock on the loop frame bikes,  the V7 Sport, and the T and T3. The G5, and Convert had iron bores. Square finned bikes=Nickasil.

I read 101592 because of the flat top stroke of the 4th digit and because the 7 on my bike's plate is very different from a 1. I can't get a clear photo now.

My T3, also built in 1975, is number 100727, making it 865 units prior to yours.

The two-letter prefix on my engine number is VD: the whole engine ID is VD*100727*. I think the "VD" will distinguish an 850 from a "1000" Convert or G5, but I don't know. As Tom Turin said, you need to see the engine number anyway, since it may not match the frame.

Greg Bender said that the letter code info here "should be accurate and correct":

VD designates an 850 T3 or T4, with chrome bores

VG means a 1000 Convert, with iron liners. (G5's came later, as did Convert and G5 engines with Nigusil bores, after engine number 215000, per Greg Field, MGBT, pages 72, 79.)
