HARVEY-V12 GENERATOR

Working on a story on one of these engines for my "Vintage Smoke" Column in Diesel World Magazine. Larry Mayer has #33 and it mounts an actual Allis-Chalmers generator. Larry says not all of them did. I'm getting info from him but since there is never too much information, I'm reaching out here as well. I have PM'ed a couple of guys that posted here but if anyone eesle has some.... Larry got #33 about 8 years back and it's now mounted on a trailer. Like most, it came out of a hospital. He says only 53 V12s were made and he knows of six survivors, including his.

 Any idea as to why its not running?

What is the latest count on survivors... and their serial numbers if possible? Larry said he heard of six. I think we can account for four here on this thread... though I had better go back and check.

I believe  Larry spoke of your generator, Calvin. He didn't mention you by name, just that he knew of one that had a different brand of generator head on it.

I am trying hard to get the production dates lined out. Looks like '72 or '73 but I'd like to know better.

Has a firm production number been established?  52-56 is the range people talk about. Larry says 53 but admits that number came from someone else.

I am researching to see what technical roots there are... i.e. is this two sixes put together? In my info, I don't see any other engines with a 6 x 6-inch bore and stroke... but, admittedly, my info on A-C power unit and generators is lacking. I have Diesel Engine Catalogs from '60 and '65 that include A-C engines but there might have been a 6x6 engine after that.
