[R-390] Fuses and tool holders

[R390rcvr@aol.com]

My information states that the switch to 3 fuse holders occurred with #2683 
in the 56 Motorola contract. The tool holders were present at least into the 
60 EAC contract, since I have specs from #1 unit in that contract, which was 
not messed with, and it had the tool holders, while the Capehart contract 
that followed did not. It is possible that the change to no tool holders 
occurred later during the 60 EAC run, but I don't have any late rigs from 
that run to confirm that fact.

It seems to me that most changes occurred between contract runs, but 
obviously not all, since the 3 fuse change was made mid contract.

Always happy to get any additional info people might have on this subject. 
Thanks
