Looking for some help with a humi

[IrishBoi]

Well hello for the first time! I stumbled upon your site today while I was looking for information on humis. I was an avid cigar collector and smoker for many years. Needless to say life took a turn and I migrated away from the lifestyle. I was thinking about getting a small desktop humi the other day. For my moms birthday I took her thrift store shopping. I think i got my omen walking into the first store. Before me stood a waist high maybe 200 count humi. There are no markings on the humi anywhere. the hydrometer is stamped "Hillsdale House". I was hoping someone may be able to help me figure out what I have and/or be able to assist me in getting it into working condition. I forgot the best part. The humi was marked $120, I got it for $60. So I think Ive gotta be back, lol. Im going to attach some pics for reference.

Thanks in advance for any and all your help.

Cheers!
