[R-390] production numbers in general - LBAD

[Jordan Arndt]

Hi group...

As I noted in my prior message, there is no way to account for what happens 
to the various parts of an R-390A or non A once the receiver hits a depot.

I've read comments about what are considered re-manufactured receivers given 
new serial tags, and while I've seen re-labelled PTO's reworked by Raytheon 
and at Tobyhanna (sp?), I've never seen a replacement ID Tag after a 
receiver has been re-manfactured...Are there any pics of examples of 
these...?
