Spotters Report
LG Marked Gas Pistons

Over the years there have been sporadic reports of LG-marked gas pistons. It is quite probable that these were made by Lombard Governor.

During World War II Lombard Governor secured over 3.7 million dollars worth of contracts mostly valves, manifolds, pumps, and gears all of which were most likely made of cast iron and more importantly non-rusting stainless steel which the carbine gas pistons were made of.

Contracts under 50,000 dollars were not included in reporting. However, there is a contract that stands out. "Gun Parts" for 811,000 dollars initiated in January of 1943 and completed in December of 1943.  Given the amount and the generic listing of just gun parts, it is probably a contract covering many smaller items.

Lombard Governor was a subcontractor to Inland for gas pistons, These have been reported as LI and L1, and it is the only known part they produced for carbines. Being that they were already making pistons it makes sense they received a "spares" contract, or maybe it was to supplement the Government Free Issue Barrel program.

If anyone has a barrel with an LG marked piston please report what barrel make it is in.

Lombard Governor

Nathanial Lombard developed the first practical water wheel governor in Roxbury Mass in 1894.

In 1904 he moved his company to Ashland Massachusetts.

The invention of the hydraulic governor was quite an innovation. Used on water wheels and turbines to prevent runaway. The company grew and made water control devices big and small for municipalities all over the country.

During the first World War, Lombard Governor produced hydraulic lathes for the manufacture of artillery shells and other special valves for the US government as well as fire control devices.

In 1943, Lombard started a chainsaw division. After the war they added plastic molding machines to their lineup.1962, the company changed its name to Lombard Industries. In 1964 they were acquired by American Lincoln Corporation and moved to Toledo, Ohio.

The Lombard complex still stands today and is now occupied by many businesses and offices.

Interesting! I’ve never seen an LG marked piston before.
