Steam & Excursion > Need info on PRR builders plates

I picked these up at a local hobby shop for $10 each. I believe that they're authentic.

What would this have been for?

The first two are easy as they show the class of the locos, one steam, the other electric. How big is the keystone?

The I1 is a 2-10-0 steam locomotive. Nicknamed "Hippos".

Do they look authentic? 
The keystone is 6 1/4 x 6 3/4

At $10 each seems like a steal compared to some prices I have seen over the years.

Yes, if they came from the railroad, that was a steal! Because  of the small keystone size, I don't know what it was used for. Are the plates full \-size and heavy?

They are full size and very heavy. I believe the GG1 plate is aluminum. 

GG1 # 4846, construction # 4290.

Served it's last days as Wilmington Shops 'snow-blower as 
a 1/2 GG1, or maybe a "G1(?)..."

You got a very good price on those items..
I'll buy them all for $100.00, tight now!

Very interesting history of the GG1. 

I'm not sure about the keystone, but everything else looks legit. Hell of a deal on those! If you were looking to sell, please let me know.

I  went to a builders plate seminar 18 years ago and I remember someone said all PRR ovals were cast by the metal pouring into the mold from a center location,  which the back of the  I1sa plate doesn't seem to show.  But if a replica,  it's pretty good.   But

The I1sa plate shows the BLW class and consecutive number on the reverse.  It's the real thing.

 

After a little bit of research I found that it belongs to PRR I1sa 4576 scrapped January 1960. Found a picture of the locomotive on ebay.
