Needing Help To Identify This Washington A140 Stamp

Great to know thanks

I too concur that the OP's original images do point to Type II characteristics. If true, this limits the possibilities to a rotary press coil or coil waste stamp. I am not inventing any new varieties, but rather made an observation that the bottom edge of the stamp appeared rough and to have possibly been trimmed. Additionally, I see no clear evidence of a watermark. Honestly, I don't think a positive ID is possible with the existing images- the stamp needs to be examined in-person.

Thanks Reedededge;
If I would say that I would be accused of inventing it also, being so bias.
I agree it should be checked out by a professional in person.
This stamp is 25mm long if that helps.
I do appreciate all the help on this crazy stamp it seems to be a hot topic.
I can see why ,a ghost image now you see it and now you don't,it would frustrate anyone.
I think finding the best way to find a watermark would be very helpful to everyone.
