That listing looks like 108's from the picture (good regs, but not what the OP asked about.

I'm in the process of moving my hobby room, but I can put one together for you. Shoot me a message if you're interested, and we can sort it out.

James,

I was under the impression that the differences between the 108 and 109 were internal and internals could be swapped, up to the s wing popped to balance the second.

Can you educate me on this one? What do you see that tells you its a 108. Am I mistaken about the internals?

Thanks!

The angle of the inlet fitting and the lack of adjustment knob tell me they are 108s. The 108 is a basic downstream valve (like the modern R190) that came as a standard 108 or a 108 HP (only difference being the HP having an adjustable orifice, vs. fixed orifice in the regular 108). The 109 is an air barrel design adjustable unbalanced reg, and the 156 or Balanced Adjustable is the balanced version. You can update a 109 to a BA by swapping the 109 poppet/spring/springpad group for an S-wing poppet/spring/balance chamber.

Thanks for sharing that info! From what I understand the 109s are a bit more dependable. Is that true.

I have a couple of low quality 109s (read - not super shiny) that are dismantled. They do require a rubber diaphragm and exhaust, but otherwise I believe all parts are there.

Can add photos tonight.

they're so shiny they bring out the covetous raccoon in me.
