WTB RCA tube tester Model WT-110A Meter or?

Yes!!!!!

Ok Cliff. All I need is a yes from you to send the meter.

Yes Bob on your photo. It looks almost identical as far as the back so now I would have a couple of options.
Just transfer the guts. or keep the guts and just transfer the bottom meter case and move my face-plate and dial-plate and front of the meter bezel and glass.  

Now the question is,Where did I put my HP Scientific Graphics HP49 Calculator with bells and whistles? Hmm, OH! OH! where is it, collecting dust?

Thanks Rod,

I must be brain addled because I was up till 3 AM for two days so only stayed in bed for 3 to 3-1/2 hours each night. (Psssst! I wont recognize how old I'm getting, as a factor.) I'll have do as you suggested as far as a shunt.

OK. Something happened and the first one didn't send. I'll try again.

Here's a photo with measurements in inches. Does this help?

Heres what i got on the web

Enter the number of inches in a form similar to 3.6785422 or 0.98742563

   Denominator desired?    16
 
(1) Subtract 2, the number of whole inches.

2.863 - 2 = .863

(2) Multiply .863 x 16 to get the number of 16th's inches remaining.

.863 x 16 = 13.808

13.808 = the number of 16th's of an inch. This is the numerator of the fraction. Apply the rules for rounding

13.808 rounds to 14 because .808 is .5 or greater.

Therefore, 2.863in. =(approximately) 2 and 14/16ths inch(es)

I tried to measure in place to save removing it.

Bob, your measurements are a very close match to my hole. I think (been a long time about 15 years LOL)
yours are-----2-3/4"  are, so converting that to 8ths of a inch would be 2-6/8".

my Measurements are by caliper of the hole as 2.863,
so it equals 2-7/8"
So its 1/8th of an inch smaller than my opening.

  2-7/8
- 2-6/8
_______
=    1/8

my caliper is marked as  0|1|2|3|4|5|6|7|8|9|1|1|2|3.........
The dial shows ->| |<- .001in at the top so the indicated number on the dial = 63

Let me know if this is a correct reading?
If so, please let me know the cost for shipping.

That Simpson meter should have a 50uA movement. A shunt of the proper value would make it a 100uA meter. You'd have to do some filing on the opening in your RCA tester to make it fit (and re-drill the mounting holes).

A check on my spare tube tester meters came up with (2) 0.5 mA meters and (1) 1 mA meter.

Good luck.

Just in case this would work. 4 5/8" across, 4 3/16" high. Unfortunately, the round back is 2 3/4". No other markings on it except the brand on the back, Bach-Simpson

It's yours for the postage if you think you can make it work. This is the closest I have in my small stash.

This would be the RCA Automatic Tube Tester Model WT-110A Meter
Clean with no corrosion that works like new.

or a

100uA 4-1/2" X 4" Square meter with the round back of 2-5/8" or less. Or similar.
