Vintage Depth Gauge - Any Info??

[atraveler4]

Hello everyone, this is my first post and I was wondering if anyone could tell me anything about this depth gauge. It has a range of 0 - 250 feet and it says "Model T". It also says made in Italy. We collect nautical items and my wife found this at a yard sale. Any info would be greatly appreciated, I'm not looking to sell just get some background information. Thanks for any assistance.

Looks like an SOS gauge.

Have you taken it out of the rubber and looked at the back for markings?

I think it is clearly same OEM that made the Scubapro. Made in Italy.

It looks very similar to the green SOS gauge in the pic, but it says "Model T" where the SOS gauge says "SOS". Any idea how old it is?

It seems to be a rubber cover on the outside of the gauge, but it is very hard and I do not want to damage it trying to take it apart. I did get the band off, but there are not any marking under it.
