Hi guys, just picked up a nice Martin & Schwartz model 80.

My question: is this a standard equipment nozzle retainer, or just an on-the-fly retrofit?

This is 1 of 3 versions of model 80 that I have & don't think I have ever seen one like this! Thanks, Rick

Some bodies add on. M&S never put these on anything. Paul www.severngaspumps.com

It thought it was too funky to be original.
