DLO Manufacturing Production Numbers

By Dan Shea

There have been four basic “Waves” of Special Occupational Taxpayers (SOT) since the National Firearms Act of 1934. While dealers may have come into the business at similar times, this description does not categorize them with other SOTs from the same era, this is simply to put some familiar names into a time perspective.

The “First Wave” was the few SOTs from 1934 to the early 1970s- J. Curtis Earl, William Vallerand, Military Armament Corporation and Dolf Goldsmith would be examples from that era. The “Second Wave” would include up to around 1982 or so- including AWC (Doc Dater), DLO Manufacturing, Jonathan Arthur Ciener, Reed Knight, Law Enforcement Ordnance Co, Bob Landies, LMO, Kent Lomont, RPB, SWD, and many others. The “Third Wave” was a major influx of dealers and manufacturers that happened in 1982-1988. Many familiar names came into the business at that time, including AWC Systems Technology, Fleming Firearms, S&H Arms, Catco and F.J. Volmer. Many of the 4500 SOTs in that period dropped their SOT status when in January 1988 we were all assessed a new tax level- from $200 per year to $500 per year, and we were billed mid year. In the following year, SOTs dropped to around 2000. The “Fourth Wave” occurred in the years from 1988 to date- it has been a cycle of new dealers and manufacturers coming in and going out, with a few sticking around for the long term. Like any other business, the Class 3 community has a turn over rate as people’s ideas either work, or don’t work, based on their reception in the marketplace.

DLO Manufacturing (Douglas Lawrence Oefinger) was a Class 2 manufacturer from the “Second Wave” of Class 2. DLO employed 2 workers other than Doug for approximately 4 years. Doug Oefinger’s contributions to the Class 3 community have been impressive. He has a somewhat combative personality and sticks up for his beliefs at all levels- and is quick to point out that to this date, he has proven his points. I have been friends with Doug for many years, and have interviewed him several times in relation to the laws that we deal with every day.

In a conversation some time ago, I suggested that the production numbers of various Class 2 manufacturers who impacted on the Class 3 community would be of great interest to SAR’s readers, and good for our historical record. Doug agreed, and he gave us his production numbers- approximates, to keep the records “Right”.

In the hopes of inspiring the rest of the Class 2s to do likewise, SAR presents the DLO Manufacturing production amounts.

All numbers are approximate, and came from Doug Oefinger as such; he did a general count, not a full item-by-item count. One other item of note, is that Doug has a longstanding Buyback Policy- DLO will purchase their machine guns back at the full price that a machine gun was purchased from DLO, once it has been three years since it was purchased from them. This is on a case by case basis, with the current NFA legal structure.

The transferable machine guns were manufactured from 1977 to 1986.
