That appears to be a 4005 shape. Hard to gauge condition from those two photos but it looks like the stem isn’t chewed up so that’s a plus. Also consider that since these are both 4 digit shape numbers, they are likely 60’s to early 70’s production, which might appeal to you. Lastly, from lurking the forum, I know you’re in Brazil. Is this for sale locally? If so, and if the 4005 is in decent shape, then yes, I think $45 would be a decent price. Try offering $35?
