Parts/Info on a Jenny Caribbean ref. 703

Hello all,

Just picked up a project Jenny 1000 with case ref. 703, with a case width of around 32-33mm. It has a cracked crystal, missing crown and minute/seconds hands.

My main question is whether anyone could tell me the measurements of the crown, width and tap, etc. and whether it had a fish logo or was unbranded?

Alternatively, if anyone does have any of these missing parts for sale, please do reach out as well.
