And just how expensive is a bubble sextant?

I discovered that real Tamaya marine sextants are available on eBay for $100-150. They were 30x that new.

My understanding is that the sextants are coming from breaker yards in India where the sextants were left on ships and salvaged.

I have one I paid $150 for. But bubble sextants are usually only used on aircraft.
