Post war military vehicles

I believe those are from Gellar Toys in NJ. He has the old Pryo molds and makes trucks and parts available in both green and gray.

These truck are definitely old like post war period as they just don't look like anything made recent years 

Also went to there website and didn't see anything like them but will contact them also and see what they said. Thanks for your input

The olive colored trucks were made by Pyro and the stamp under roof will also have the words "made in USA", which is original issue from mid 1950's.  They were never reproduced after that.  The gray also should have "Made in USA" to differentiate from "repros", which will not have "made in USA" in the logo.  

The reference to Geller Toy may be who is manufacturing the repro trucks, tanks, & extra parts.  If the logo does NOT have the "Made in USA", it is repro, and holds a far lesser value than an original.  They were issued in 1958 Military sets which if memory is correct, Set 1591 & 1595.  Set 1595 should be lead by the 1625 switcher, 6804, 6806, 6808 flatcars, 1625T (with Timken trucks), & 6017-85 gray caboose.  It is a premium set if all components & boxes are there.

My mistake, I thought Gellar's trucks and parts were made in both green and gray, apparently only in gray, so your green truck is original Pyro. These were available in five and dime stores back in the day.

Chuck is correct that back in the 1950's, you could buy the Pyro items in 5 & 10 stores, and toy stores.  Lionel decided to use them in Military sets as stated above.  The Olive trucks are considered Army, and the Gray trucks/DUKW/Tank were considered U.S.M.C. issue, even though the medical truck has Navy on the side.  The U.S. Marines are actually considered part of the Navy, and the logo on the medical truck door shows the Marine symbol.  As stated, if it doesn't have "Made in USA", it is a definite reproduction and not original.

The USA is visable as is Pyro and the made in is hard to make out but believe it also is there on all 4 trucks I have

Lionel used grey trucks on their flatcars. The green ones were not used by Lionel.
As others have posted, the Pyro trucks were sold in green as toys in toy stores and/or 5&10's.

Informative post.   A family friend gave me what was left of his trains from his childhood. No engine or caboose and some missing parts and a missing flatcar.  Need to start searching for some replacement parts. 

You can also tell if the vehicle is original by gently rubbing your finger over the Marine Corps emblem. The repros are silk-screened, the originals are heat stamped. The original will feel indented,the repros smooth. Hope this is useful to you.

The stamped logo under the roof is the absolute proof of original.  Reproduction has the "Made in USA" MISSING!!!!  The outward stamping means nothing versus the above mentioned reference.
