Cezch M34? Finnish M40? or Swedish m37?

Hi. I've been offered this helmet. Seems to me like post-war painted. I can't really identify the helmet. I did some research but I can't pinpoint which of these three it is Cezch M34, Finnish M40, or a Swedish m37? Either way, the value isn't high so it could be a fun project to try and remove the new paint. Seller says the are no markings. Inside is written "Karin kypäpä", Kari's helmet.
