11 Set stuff

[cletrac (RIP)]

Some of the ebay spare parts cases have the embossed lettering and are 5C for the 19 set. With not much effort with a hammer and punch the C could become a B. The others have no lettering and would need a decal or a stencil. I have no idea which ones I'll end up with but they'll both become 5B cases.

Here's a list of the spare parts case contents from the operator's manual:
Ammeter H. F.
350 mA No 1
Brushes, D or M, No 4
Brush holders No 5
Brush sash tool No 2
Bulbs, 6V J (4 req)
Lamps, operators, No 2
Tablets, calibration
No 1
No 2
No 3
No 4
No 5
Voltmeter, pocket,250 volts, No 2
Case for meter

I have the voltmeter and case and the operator's lamp.
What's the brush sash tool?
What are the calibration tablets?
The left picture is one of a 5B that Bruce sent me. The dividers are riveted in place.The right picture is a newer 5C but it's the same dimensions and I put my voltmeter and light into place. In Bruce's the green circle obviously holds the ammeter and the compartment on the right is for brushes and the other small bits.
