I have been compiling a list of "out in the open"/"currently accounted for"/"surviving" Quincy Looper serial numbers so as to get a handle on how many are left and of what class. I don't have the pedigree for the fast majority of the engines, it is not the point of this little project. All of this information has either: a) been obtained by people mentioning their engine serial numbers online b) having people tell me their serial numbers or c) seeing engines in person. I do have names of the individuals who own some of them, but that also is NOT the point of this project. I will NOT publish who owns these engines; honestly for the ones I have already it really doesn't matter because anyone who really cares can simply do a Google search and find out who posted it out in the open. But, for any serial numbers people send me directly, I will assume unless told otherwise, not to publish.
Again, I have compiled a list of "currently discovered/owned/accounted for" Quincy Loopers. If you would like to participate you can PM me the numbers you have and I will add them to the list. Here below are the known serial numbers that I have according to class. Sidenote: For "F" class engines, please tell me if it is a 4 cylinder 44ci, 6 cylinder 60ci or 66ci, or "D and a half" engine. If it has serial numbers of the D or B engines to make it that would be nice to know. Thanks!

*************************************
Some additional information provided by Paul Christner to give a better idea of total production numbers:
O. F. Christner stated that Quincy Welding built a total of 759 Loopers between 11/30/63 to 7/15/76 when a newer model (the Quincy Z) was designed. The number of engines made was as follows: FA = 218, FB = 243, FC = 103, FD = 121, FX = 74.
As to the engine numbers, the only thing I would add is that the F numbers of 74 in total was made up of both 44 ci Alky Deflector and Looper designs. The same with the 60 ci and 66ci engines, both Alky Deflector & Looper designs. I do know Quincy made a total of 2 66 ci Loopers, and only 1 is in existence. Which totals 759 engines, plus 3 90 ci Looper engines (known as The Beast) of which only 1 may exist somewhere in the midwest. It was used in a tractor for mini-tractor pulling events. So that makes a total of 762 engines - which does not count the 1881 Quincy Mercs that were strictly Deflectors (both gas and alky) that were configured prior to the later 762 total.
O. F. Christner was well known as an innovator in racing and outboards. According to Christner, Quincy Welding produced a total of 1881 Merc Alky engines between 1/10/48 and 3/15/63. He stated that the number of Alky engines built using all Mercury parts which had padded cylinders to bring up the compression ratio to 14:1 for alky use was broken down as follows - A class = 349, B class = 463, C class = 311, D class = 430 and F class = 328.
I would add there were at least 30-40 other non-numbered engines made as R&D motors for the shop. Some were sold, some were replacement engines for customers, some were scrapped after testing.
That does not count the Quincy Z engine production, as those records were lost in the move when the Quincy Welding/Precision Machine building was sold in 1984.
So that totals 2683 engines under 100 ci from Quincy Welding/ Precision Machine not counting the Z's.
Note: some of these engines were re-configured from core Mercury engines sent to us at Quincy Welding to be made into Quincy Mercs, and some of those were Quincy Mercs originated from us at Quincy Welding, where we supplied the Merc block and crankcase also. However, all the Looper and Z engines were created by us at Quincy Welding, then later Precision Machine with the Z production.
Final point: These numbers above do not include all the Quincy Modified engines made up of various configurations that were over 100 ci in displacement. I am still trying to compile all of the production information on those engines.
