Stew...
All refrigeration pressure gages are bourdon tube style...
Probably the new guts from any number of them would work with some tinkering...
Pressure range and physical size would be the key stats...
The original frame and face could probably be reused ..with new guts..
I probably could find some thing that we could cobble together that would work ,if you bring it with you or send it up..
I assume it is for oil pressure..
If the bourdon tube it'sself is ruptured,it can be resoldered with Staybrite silver solder,low melting point..430Deg.F...with a soldering iron..
I've been using it for a zillion years and every mechanic should have a bunch of this around...steel to brass,copper to copper steel to copper..brass to copper..
Great stuff..

Stay-BriteŽ Silver-Bearing Solder 1 OUNCE KIT
The premium solder that solders all metals except aluminum (including stainless steel and cast iron). It flows freely and has over twice the tensile strength of regular solder. Melts and flows at only 430 degrees F, providing strength without distortion. Includes a 1/2 oz. coil of solder and 1/2 oz. bottle of flux. Can be used with soldering iron or torch. Lead free.
Versatile Stay-Brite silver-bearing solders are used throughout industry as a better-than-brazing method in many instances.
The important advantage of Stay-Brite solders is the greater strength of the overall component after joining. Their lower working temperatures eliminate the weakening of the base metals caused by annealment from high brazing heat.
Stay-Brite silver-bearing solders have the same excellent affinity as Stay-Silv and Safety-Silv to bond with all the ferrous and non-ferrous alloys (including stainless steel, nickel, copper, brass, etc.). Stay-Brite joints exhibit considerably higher-than-necessary elongation for sound dissimilar metal joints and vibration applications. Stay-Brite alloys range in temperature from 430°F to 535°F.
Stay-Brite offers these important advantages over silver brazing:
Lower material cost - up to 3 times
Lower temperature - up to 3 times
Faster production - up to 4 times
Faster post cleaning, little metal discoloration.
Elimination of base metal distortion.
Elimination of base metal annealment
Elimination of oxide scale formed by heat.
Cadmium-free - non-toxic.
Lead free
Acceptance by The National Sanitation Foundation
Stay-Brite has been used for over thirty years to join refrigeration/air conditioning tubing. This alloy has been used to fabricate millions of strong, leakproof joints. Stay-Brite connections are excellent for many HVAC applications.
