Thanks for your suggestions and assistance. Based on the description we have of the of the Arms, what would be your interpretation of the blazon? I am inclined to think that the "half moon shapes" should indeed have the cavity facing the dexter side: Increscants as the description says, not crescents, and that the spear was part of the decorations surrounding the shield rather than a charge on the shield. However, I am by no means an expert in this field and may be making a big assumption based on what I read in an heraldic dictionary. What do think? Also, what do you make of the crest? Should it be included in the achievement since it does not appear in the blazon?
I would be very happy to have a rendering done of these arms if you have the time.
Your help is greatly appreciated, :-)
