One Week's Pay for a Roman Soldier at Veii

My interest in Roman pre-money started when I read Rome paid soldiers for the first time at Veii about 400 BC, or a century before they started producing coins. A century earlier, Servius Tullius classified citizens by wealth.
If bronze ingots were used for money, how were they measured. It seems likely that steelyard scales would have been used. They are better for weighing heavy items than the double balance scale.
The following pics are from my display at the Texas Numismatic Association (TNA) meeting in June.

 The display shows one week's pay in the large pan of the steelyard scale = 21 Asses = 6900 grams = 15 US pounds. Rome did not produce coins in 400 BC. The pan includes some cast bars, cast cakes and Aes Rude pieces. 

Pages of plates from Haeberline, see pic and info on the book below, cover the bottom of the display are. Some pieces not needed to make 15 pounds of bronze are shown. 

This double pan balance holds half a day's pay or 1.5 Asses. The scale weights in the left pan weigh one As and one Semis (= S = VI VNCIA = 6 Roman ounces). 

Haeberline's book and plates.

Hab plate 21. This must be a blue state set of Aes Grave, the prows are pointing left and they weigh less. Prows pointing right weigh more.

Roman scale weights, the left one is 6 ounces and could be Republican, the right one has a portrait that looks like a LRB (late Roman Bronze, or 3rd centruy AD) to me.

I bought this Roman Steelyard scale as a lot of two pieces. The weight has a portrait that looks like LRB. The balance arm could be older or newer.

Several weights that could be used with a steelyard scale. I have the one in the lower right on the balance in the picture, but the scale is held by a second hanger to keep from having problems in the case. 

I tested my scale using windshield washer fluid before building the display.

A few more pics for good measure:

Barrel Shaped Bronze Scale Weight, 326 gram, with Silver Inlay

Barrel Shaped Bronze Scale Weight, 326 gram, with Silver Inlay
This weight is the largest of three scale weights I purchased recently. The seller's pic, Timeline Auctions, is below.  A similar 326 gram weight sold 3 months earlier and is the 2nd pic below. Both were advertised as Viking, but look a lot like Roman barrel weights. They have the right weight for a Roman pound or As.

30 - 31 mm top and bottom (small) diameter

Provenance - From an old North Country collection; formed between 1970-2000.

Literature - See Weber, K. Byzantinische Münzgewichte: Materialkorpus für 1-Nomisma-Gewichte, Schwelm, 2009 for discussion.

I asked the seller why the weights were listed as Viking when they look a lot like Roman / Byzentine weights. He said:
The Viking weight was attributed as Viking as it was found from a Viking site/context. The Vikings regularly re-used Roman and Byzantine trade weights for their own purposes. 
I think my weight has a wolf design on part of the top. Below the design (wolf and twins?) is a horizontal line and letters. 

the top of my coin, you need a good imagination to see the wolf

I think the wolf looks a bit like this one.

Side view, this color looks about right. The two pics above had extra light to try to bring out the design.

I have not decided if cleaning would improve my chances to see the design on my weight. I am inclined to leave it as is.
