Case 300 round nose B H

I bought this in a estate with about 35 other items. I would like any opinions about what it is worth ,. Say's 300 on the hood but the tag say's G 310 W This hoe hasn't been used in years I pulled the head & sent it in , shop said it had just been done & just needed cleaned up. The sleeves looked like new. It starts & runs good but needs the carb cleaned( I had to back out the load adj over a turn to keep it running w/o choke) You can measure the dried grease in inches around every zerk It was taken care of. it is not beat up but the dash is rusted out at the bottom. There has been a few minor welds on the hoe & the loader doesn't show any If I was going to use I would put new hoses on it .Tires are good Thank you very much for any help Larry

My guess is $3500-5000. Depending on how bad someone wants it.
