DM3 adjustable breech value

[Alexndl]

I got it not too long ago a DM3 that was used with a Qloader setup
the breech is in two pieces and ca be tiled each way at 45 , can be use vertical or warp feed style

I have understand it was somewhat rare and would like to know a value?

those were made by tarantula mfg, value im not sure, its blind so its applications become a bit limited by that,

I would say somewhere between $20 and $40?
