Propane 90 Degree Adapter

Years ago I bought a propane adaptor to use with a bigger tank for a barbeque. I never got around to it. I just found it still in the package while cleaning the garage. It looks like it is used to turn a sideways propane tank valve into an upright valve. The picture shows it being used for a lantern or heater? New ones are plastic, this one is brass. I think I paid $57.00 years ago. How does $20.00 sound? Also have a female brass coupler and male brass end for Barbeque? $57.00 on Amazon. How does $10.00 sound?
