Anchor (Cathead?) rigging for Slocum Spray

[Pete44]

I'm a new member working on a Spray kit from Bluejacket. I'm trying to add more detail to the anchor rigging than what's provided in the original kit but after much internet research cannot find any information on how the Spray (or similar smallish 19th century sloops) would have secured the anchor. Photographs of the spray show the anchor secured from the port side of the boat but I cannot make out how it is secured. It doesn't appear that the Spray used an actual cathead with associated blocks, lines and securing paraphenalia etc. Other modelers who have posted their completed Spray builds on the internet seem to have dealt with the anchor by placing it on the deck unsecured to stanchions, eyepins, etc. Does anyone know how anchors were secured on Spray-type sloops?
